Write to location 00000000 caused an access violation.

[And The Pickles]

The pastebin attached is the error log and I also attached a second pastebin with my dxdiag. I was playing exactly 2 hours ago. I logged out then came back later could not log in kept getting error messages. I play through steam. I tried clean deleting and reinstalling. I tried moving to the x32 bit version although I thought that would be a stupid idea since I'm running x64 at all times. There's nothing wrong with my disk whatsoever.

Please give ideas for help I'll try things. I even deleted the 7 days to die in the registry folder before trying to reinstall through steam.

7daystodie.exe caused an Access Violation (0xc0000005)
That's the important thing, along with write to location 0.

This can be solved two ways;
a) Disable any other overlays (but the steam one that is), MSI afterburner has been a villain the last year. Some have reported Nvidia game overlay to mess stuff up.
b) bad/old/corrupted drivers, meh... probably not, more likely to be option a.

Although with that said...
If you scroll down to row 153 in your error log it says:
C:\Windows\SYSTEM32\nvoglv64.DLL
Yeah, no. That's no good. It shouldn't say "gl" there, that's OpenGL. That was used with the Voodoo cards back in the -90's, ID Software still makes a few games optimized for that. That is for Macs & Linux machines nowadays.
So, in the launcher there's a thing called "Use OpenGL renderer" or something similar, untick that box and the game will default to DirectX instead.

So between those 3 things, one will 100% work and solve your issue.

[And The Pickles]

okay let me try the open GL and get back to you!

[And The Pickles]

Interesting development. I used the launcher to change the settings OpenGL was unchecked. I'm guessing my graphics card automatically forces it. I'm wondering how that may have happened first of all since I was playing it fine a few hours ago and secondly how to enable DirectX

[And The Pickles]

Ah wait it was directX that was the issue. 7DaystoDie switched to my alternate graphics card by itself. So thank you for your help! :)

[Tokfan]

Yeah, that's a major pain in the butt when it comes to laptops.
Sometimes it just defaults back to the on-board one, and when that happends you can bet the drivers aren't up to date and you get some issues.
Usually after a nvidia experience update, because... who want to keep their settings right? ;)

[And The Pickles]

I always have to switch back to the NVIDIA after every single update like okay thanks windows or whoever you are that is doing this to my PC. Sure the intel card is ok but it isn't NVIDIA. Sheesh. laptops right?! >:[

[Tokfan]

Well, you could always update the intel ♥♥♥♥ drivers, then your game won't crash but run at a cinematic 5 fps, or well... just turn off those nvidia updates and tell windows to shove their gfx drivers up somewhere where the sun doesn't shine.
Works until you buy a new game or you experience crashes with your current. I'm still on gfx drivers from 22/8-2017, they work and nvidia & microsoft has been really annoying during the last year releasing non-func drivers.
When I run into issues I'll try new drivers, until then I will not touch stuff that ain't broken.

[And The Pickles]

Idk I really like the Nvidia drivers for all my other games. D: intel is okay but you know NVIDIA makes everything look way better.

[Shy]

so what do you do if you get this exact issue, your drivers are all up to date. and doing all of the suggestions here doesn't work?

[And The Pickles]

Well I reinstalled steam completely after a while because guess what? 7 days to die was the reason my computer was derping. I emailed the support people waiting for a response still. It gave me a virus too. like wtf?

[And The Pickles]

Another thing that I did was downgrade my graphics driver to an earlier release. but also lost all my saves doing the steam thing. so that was bad.

outoput_log__<datetime>.txt would be more helpful than the error log file.
In the steam client.
Right Click 7 Days To Die and select properties
Click the Local Files Tab
Click the Browse local files button.
double-click the \7DaysToDie_Data\ folder
open output_log.txt Or the latest output_log_<DATETIME>.txt where <DATETIME> is the last date/time found in the filename.
