Game crashes at level load with Access Violation in UnityPlayer.dll

[Cyric297]

I've experienced multiple crashes at level load with access violations.

I'm running an Intel Chip, with an RTX 4090, Windows 11. The exception details are thus:

Faulting application name: DRG Survivor.exe, version: 2022.3.7.27451, time stamp: 0x64c8e4e6
Faulting module name: UnityPlayer.dll, version: 2022.3.7.27451, time stamp: 0x64c8e7d3
Exception code: 0xc0000005
Fault offset: 0x0000000000a83b91
Faulting process id: 0x0x5F94
Faulting application start time: 0x0x1DA62132D514F97
Faulting application path: C:\Program Files (x86)\Steam\steamapps\common\Deep Rock Survivor\DRG Survivor.exe
Faulting module path: C:\Program Files (x86)\Steam\steamapps\common\Deep Rock Survivor\UnityPlayer.dll
Report Id: 42aa85f5-d5ce-490d-97ee-26cdd221ec0b
Faulting package full name: 
Faulting package-relative application ID: 

Debugging the error leads further down the rabbit hole:

Unhandled exception at 0x00007FFAF9513B91 (UnityPlayer.dll) in DRG Survivor.exe: 0xC0000005: Access violation writing location 0x00000055C1480000.

and looking at the stack trace, this looks as if some amount of code is trying to access unwriteable memory.

>	UnityPlayer.dll!00007ffaf9513b91()	Unknown
 	UnityPlayer.dll!00007ffaf9513f4c()	Unknown

 	kernel32.dll!00007ffbee75257d()	Unknown
 	ntdll.dll!00007ffbf026aa58()	Unknown

instructions at that location:

00007FFAF9513B91  mov         dword ptr [r11],eax  

So, at least according to my system the crash is occurring because the memory location at r11 (in my case 00000055C1480000) is not writable, which is probably correct and thus the exception should be thrown.

Every crash seems to be at the same place, on map creation:

I get the same-ish thing (posted here, but not with this output until I looked at yours) https://steamcommunity.com/app/2321470/discussions/2/6292161380819014151/

The interesting thing I'm seeing among a lot of the crashes (not all) is either a 13900K or a 14900K combined with a high end Nvidia GPU and a large pool of ram.

I need a guinea pig to test a bunch of things:
Core parking enabled/disabled.
Ram reduced to an average level (8-16GB)
Framerate caps to a reasonable level.
Monitoring system temps of the CPU and GPU.
Undervolting the GPU and insuring it's stable in a synthetic benchmark.

So I may have found a fix, I've been able to play the game now for an hour or so with no crashes (previously I wouldn't last 15 minutes).

In the Player.log file, I found some more crash details:

ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.' (Address: 00007FFB84BD401F)

So I decided to search this error which lead to several old threads on the Unity Boards (and a few on Steam as well). Seeing that the error appears to be originating from UnityPlayer.dll, I assume it may not even be related to DRG at all. So somewhere in these threads someone mentioned updating to the latest BIOS update solved their issue.

There was an update available for my bios so I went ahead and updated it plus all my chipset drivers for my motherboard.

Anyways, after that, at least so far, I am not running into the same issue. However, I am happy to help you troubleshoot if you'd like, or if I end up having the same problem again.

Got it, I'll make a note of this as a possible user end fix until Funday can resolve it on their end.

[Cyric297]

Unfortunately, the crash came back. I had most of my success running the game after a clean reboot (installing drivers). I think there may be a conflict with some of the other software I am running. Either way, it looks like I'll have to wait for a fix from Funday or just reboot prior to playing the game. If you'd like to run through any of your troubleshooting scenarios, let me know.

[The Loan Ranger]

Someone on the discord may have found a fix. Unfortunately it'll reduce overall system performance, but it's worth investigating.

I've resolved the bug - it looks like newer gen intel cpu's such as 13900 or 14900 are using Intel Turbo boost to overclook. Once íntel turbo boost for CPU is turned off, it worked without any further crashes. Anyhow, this beats the purpose of those CPU's by loosing a significant amount of power. There are some threads about lowering the P-Core multipliers which should allow to turn intels turbo boost back on again.
