Random Crashes - Access violation (0xc0000005) in build cd937a0ba267

Hey there, I’m here to provide information on the Access Violation crashes on my end, in hopes this will help resolve the issue for me and others. I will also be including what I have tried on my end to avoid getting the problem.

Edit: After I first encountered the issues no mod whatsoever has been in use and to be sure I unsubscribed from all of them as well

I have done the following as well:
Firstly I was on W7:

  • Thread count adjustments
  • Updated drivers ( not clean)
  • Closing unnecessary apps

After upgrading to W10:

Sidenote: noticed significant improvement in FPS after going from W7 to W10. Previously ~40fps on DX11 low settings > 60+ on medium DX12 post-Win10 upgrade.

Not in exact chronological order!

  1. Fatshark guide to checking system for errors etc
  2. Clean latest GPU drivers reinstallation
  3. Steps I followed to avoid the access violation errors.
  4. Tried different “Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows > SharedSection=SharedSection=1024,20480,yyyy” yyyy values (original 1024 > 2048 > 4096 > 12228) as suggested on AutoDesk forums.
  5. Clean Boot
  6. Thread adjustments
  7. GFX settings adjustments
  8. AMD Software not running any ‘enhancers/optimisations’ for games
  9. Uninstall and reinstall (maybe something leftover in registry from previous installments thats conflicting?)
  10. BIOS version checking, running the latest version available for my MOBO.
  11. No connection between hosting and joining others’ games.
  12. Adjusted page file sizes from auto, to previously 1.5 of my RAM as initial and max to current seen in the logs.
  13. Kaspersky scan, Malwarebytes scan which revealed only PUPs.
  14. Stopping non-Microsoft services.
  15. Tried adding compatibility options and/or Run as Admin on Launcher, dx12 exe.
  16. Running with Dx11 or Dx12 doesn’t change anything besides FPS.
  • Haven’t encountered this/these problems in other games.
  • Game is not located on same drive as OS.

Two recent console logs from the crashes(they all have same case as in title):

Doesn’t seem to be any connections for the occurrences in the logs for this prior to access violations, but I’m not a dev ofc.
Console logs I uploaded to ufile as 7zip

[Log end]

Event viewer log of the crash:
No errors or anything that would stand out during the crash in other logs.

Update: Managed to play a half of a campaign in CW and a full one right after without crashing while using only 3 threads (half of actual cores) and what was interesting that in the end of the legend CW campaign scoreboard it was as if I had crashed up until the last mission or so and had 90 kills in total, 2 specials, whereas that cannot be true as I killed upwards of ~20 specials in one map at some point. Maybe this can help pinpoint this matter further.

Wow, this is the most detailed report I’ve ever seen!

Did these crashes start with Chaos Wastes for you, or prior to that?

Thanks! I think? I guess I really don’t like when things aren’t working as intended. :thinking:

Prior to Chaos Wastes the game was running fine on my system. Would crash dumps help out as well or are they just console logs written differently?

Update: In my case it seems to have been overheating/overclocking that caused the access violation errors. I did a thorough clean on PC today, applied new thermal paste and downtuned to 4ghz and managed to play 3 CW campaigns in a row without crashing using 3 threads.

That being said, from past experience and having run 8 threads before just fine, I think something has been left unoptimised or god knows what, as temperatures at even lowest settings are pretty high. I’m saying this after the first time around i got crashes every 2 minutes, seems to have been uneven thermal paste/MSI afterburner. I was more worried about temps before but i’ll keep an eye on CPU usage tomorrow, but the cores were definitely not being utilised at high %'s.
