Valheim crashing on startup

[Valboose]

Bought valheim 2 days ago and it crashes on startup, i get to the Valheim logo and then it just crashes, I get a unity error "valheim - unity 2019.4.24f1_5da6f0345e82" I haven't installed any mods and have tried running in admin and using steam commands in the launch options too, disabling steam overlay didn't help but I now know that this has broken any unity game I try too run, because I could run them fine before but after downloading valheim none will open. I will leave a link of my player log below in case anyone can read it (alas I cannot) Any help is greatly appreciated, Thanks :)

Some suggestions...

1. Try installing on a different hard drive. This oddly fixed it for another member I had suggested to.

2. According to an old thread at the Unity tech forums, it seems this could also be caused by low RAM. How much RAM do you have? Are you running any active programs besides Valheim?

3. Make sure your GPU is updated to the latest drivers, via the manufacturer's website. This seems to be the culprit for some people's crashing.

According to this thread: https://forum.unity.com/threads/u5-3-error-symgetsymfromaddr64-getlasterror-attempt-to-access-invalid-address.413565/page-2

One of the members stated:

"I'm happy to report that our user found a fix:

"I updated my graphics driver, then took a look at all the devices connected to my PC and disabling them. Turns out there was a wireless device that seems to be the cause of it.
I never needed to take it out before so it didn't cross my mind until you mention adapters. Weirdly specific issue, but it looks like everything is fine now!"

We use InControl (version 1.6.11 build 8842) for Input and sometimes it seems to have issues with USB devices that are not controllers. Very specific, but mystery solved for us. "

I had been playing valheim for about two weeks now, then recently i started running into issues, right now, the most pressing one is literally a full system crash (blue screen of death) whenever trying to load a world. I get a error called "UNEXPECTED_KERNEL_MODE_TRAP" shown on the blue screen as the reason, might be an unity error, but im not sure at all.

I updated all of my drivers, rolled back updates, tested different graphic settings in-game, all were for naught. All my other games seem to work just fine. I suppose i'll have to wait until irongate optimizes this game better,

It was bad enough to have to deal with Valheim literally disabling my GPU before(this is another issue I know even less about, it simply used to crash the game, then it would somehow disable my GPU from working, running everything afterwards at 0 FPS, or making other games unplayable because "I have no graphics card running", have to literally reset the computer to solve it, except that Valheim would do it again, I jsut had to NOT play valheim in irder to be able to keep my GPU intact if I wanted to play other games)

In the end... this game is great... but there are some serious issues with it.

According to a website:

"An UNEXPECTED_KERNEL_MODE_TRAP is a problem that appears in the BSoD, and it is mainly caused by a bad or outdated driver. The logical consequence would be to update the drivers."

I'm wondering if you updated your GPU drivers from the manufacturer's website or through Windows update. I found that Windows update usually don't pull the latest drivers and should go to the GPU's website to manually update them.

I have updaed, installed, uninstalled and repeated the process through the official NVIDIA web pages, I already said this on my first comment didnt I? I have done it already 5 times already trying diferent things and methods. it doesnt work.

Firstly, I understand you're allowed be annoyed, but I'm a player and don't work for IronGate or NVidia. I was just trying to help. If you prefer I don't, I can just stop. Your behaviour is uncalled for. I want to help other players, so they can have fun too.

Secondly, you never said you went to the official NVidia website. This is what you said:

So since I cannot assume you went to the official site, I suggested you do, because most people do Windows Update instead.

Now, as for another possible solution, have you tried uninstalling the driver, and making sure all older files are also uninstalled, AS WELL AS make sure the driver installation in the registry has also been deleted? There may be residue stuff in there that might be causing the crash.

[Komyeta]

I thought that mentioning that I retried the same thing over 5 times using diferent methods would cover it up. Bah, fine, you're right, that came out harsh from me. In any case, yes, I completely uninstalled the graphic drivers prior to reinstalling. Not sure about the registry thing though, not a clue.

Here are some further ideas related to the TRAP BSOD. Just some guesses based on some stuff I read online.

1. Maybe a loose GPU? Turn off your computer and push the GPU into the motherboard slot firmly, then disconnect and reconnect the power to the GPU card. See if any other hardware is loose as well and do the same.

2. See if other drivers, not the GPU, need to be updated as well.

3. Run Windows 10 Integrated Memory Diagnostic Tool and check if your RAM is totally fine.

4. Run SFC and CHKDSK as an administrator.

5. Make sure you have enough disk space where your C: is located, since the world is saved in the appdata folder.

6. Maybe install the game onto a different hard drive? I suggested this to someone and this fixed it for them, but might not be of the same type of error you're getting.

I am aware these seem so arbitrary, but according some people who had fixed the TRAP issue, these were some of the things that helped them.

Tried reinstalling on both my SSD's and HDD, also I have 16GB of ram, have tried closing everything except valheim and opening and my GPU is all up to date with drivers from geforce experience

[Komyeta]

I never tried so hard to make a game work before, I did all I could, followed a dozen suggestions, tried them back to back and nothing works, its just BSoD after BSoD. Not worth risking my machine's integrity over it, time to forget about this game now and uninstall. Maybe revisit it back in 6 months or so till the geeks at iron gate figure out how to actually optimize it properly.

For both you and Komyeta, I don't know what else could be done to help solve this.

So far, I haven't ran into any of these issues that many people are having. The game crashed on me once pre-H&H, but that's it. I'm assuming this is specifically an Unity-engine problem, because apparently, Subnautica has the same type of problems for some of its players.

According to this thread for Subnautica, it seemed like it could be an Unity issue. https://steamcommunity.com/app/264710/discussions/0/618453594753368594/

But here's the thing. BSOD's usually happen because of hardware and bad drivers. If a game is triggering it, it mostly means it's not the game itself that is the problem, but something in the game is triggering something that's already bad with your computer. Make sense? Kind of like an allergic reaction. Normally, you eat steak and potatoes (other games), but then eat lobster and spaghetti (Valheim) and your body (the computer) reacts negatively to it. Not the best analogy. ^_^

Specifically about lowering the frequency of your RAM or CPU overclocking. This might fix it for you:

Someone also mentioned they were getting BSOD because their GPU fan wasn't turning on at higher temperatures. So they fixed it by installing a GPU/CPU fan monitor.

I did hear about subnautica having issues too, true, maybe Unity then, but still, nothing else I can do to try fix... whathever is wrong. I jsut took the short straw on this and have issues, others dont. Thats it, jsut gonna accept it and wait.

anyone ever figure this out? weirdly i was able to play Valheim decently (with some occasional stutter issues) between March and August of last year. Tried it today and I'm getting the same error when trying to load worlds. Too bad I wanted to check out the new stuff.

In the end my issue was hardware related, technician I went to said he had to replace a burnt transistor or something. Problem was fixed for me after that. Sorry I cant help further than this.
