DCS Crashes at "Waiting for pooled tasks - 1" Every time, reguardless of Aircraft/Map/Mission

[sabreman]

Good Afternoon,

Like the title says, my game crashes at this step regardless of what aircraft, mission, server, etc I'm using. I'm able to get into the game and use the mission editor, but trying to actually start anything results in this outcome. Attached is my crash log.

This is on a brand-new (clean formatted) and fully updated windows 11 install with a brand new DCS install. The only module I have currently enabled outside of the default free ones, is the hornet. 

I have ran memtest and verified that my RAM is fully functional. I'm on the Latest BIOS drivers and NVIDIA drivers. Page file is system manged. Both the Saved Games, and the main DCS folders are exceptions in windows defender. This computer with the same hardware, used to work flawlessly a few months back. 

 

Please let me know if you need more information.

Looks like an authorization issue, check that your computer date, time and time zone are correct, and that you are using the correct dcs account password.

[sabreman]

I've done that, and have the same result. Attached is the new crash log.

not the same result, the authorization error is gone and there is a new error:

 

EDCORE (15212): # C0000005 ACCESS_VIOLATION at 00007ff837d8eff3 00:00000000

 

your windows has a very small swapfile, try your increase it to at least 32 GB, here is a guide if needed:

Error is the same as the one in the first log you provided:

Your page file is fine, you have 64Gb RAM.

Based on the DCS log analyzer, and yes I realise this is a new install but things can get corrupted, it has the following advice:

• Run a slow repair, including the option to remove files
• Delete Saved Games\DCS\fxo and metashaders2 and try again.
• Next, delete %LOCALAPPDATA%\TEMP\DCS and try again.
• Next, try renaming Saved Games\DCS to DCS.old and try again. Make sure to rename and not delete so you can get your bindings back from the Config\Input folder

The DxDiag report also shows some issues:

Windows Error Reporting (WER)

Application Errors

DCS.exe: c0000005 (edterrain4.dll)

Memory Timing Issues

Remove any overclocking (XMP) from your RAM.

Try the above and then provide another log file.

 

EDIT:

I see you're on Windows 25H2. Was your previous install on this as well? Haven't seen any reports of issues with this as yet (there's a forum thread here with people stating theirs is fine so far), but something to be mindful if folk see similar issues / stack traces.

I have completed all of the above steps to no avail. XMP was not enabled. And yes, my previous install was also on this update.

Attached is the most recent crash log.

Any ideas? I've been unable to play DCS for a few weeks now because of this issue. 

 

Edit: Out of desperation I've un-installed the hornet and reset all my settings to the lowest possible, and the game loaded! I got like 4 frames of gameplay before it crashed again. Note, this was the first frogfoot instant action mission, which I've tried before. 

However, this is definitely progress and the new crash log is attached. Seems to be the same terrain engine error as before. I'll keep editing this post as i keep troubleshooting.

Have you tried RENAMING your DCS Saved Games folder (re-install won't have touched it).  You've got some weird errors showing up in it (even in the latest log) that could be causing issues.

[sabreman]

I've reinstalled my whole OS friend, which included a full drive wipe, and yes I have ALSO tried renaming the folder. 

As a follow up to my last post, it seems that the crash is now somewhat random. The same mission now crashes on lodaing world assets or whatever. Seems like a race-condition of some kind.

I'm on the Latest BIOS drivers

Please let me know if you need more information

Did you update BIOS before these issues started?

[sabreman]

No. These issues started on my previous install with outdated BIOS drivers. I hadn't fired up DCS for like, 2-3 months and when I tried this whole shtick kicked off. I thought a complete wipe would solve it, but here we are.  Quite the problem.

[sabreman]

Just as a troubleshooting idea, and because I have literally no idea what else to try, I made a brand new DCS account and tried the game with it (and everything but the base free modules removed). Same outcome, no dice. 

[sleighzy]

Latest log contains the following during startup. You had a similar one around vc_options.lua in the first log. I'm looking through the others.

Can you check if that file actually exists. It does for me so don't know if it's a permissions problem. You don't run DCS, and have never run DCS, as an administrator right? Never even ticked the box "Run as administrator" under the Compatibility tab of your properties on the shortcut or exe file in the bin folder?
