Consistent BSOD due to BEDaisy.sys (BattleEye)

Community Technical Support

Over the last few weeks, I’ve been getting more and more BSODs during gameplay. As of today, I can no longer go longer than 1 match of Ground Battles without suffering a BSOD. The error message is entirely consistent:

ATTEMPT_TO_WRITE_READONLY_MEMORY

In Windows Debug, it always points to BEDaisy.sys as the culprit.

One thing I suspect is it due to my laptop utilizing an Intel i9-14900HX CPU, which has a record of being faulty, however if this were the case I’d expect to be crashing throughout the entire game. Instead I am only receiving crashes when playing Ground Battles, in the Ground Vehicle Hangar, or Test Driving with Ground Vehicles. Air and Naval game modes and Hangars seem entirely unaffected. (for now)

I have run various tests- Windows Memory Diagnostic, memtest, OCCT Extreme, Scan File Checker (SFC) and DISM. None of them resulted in any issues with RAM or CPU.

I do not have a custom hangar or anything, and the BSOD occurs even with vehicles and lineups that contain no custom skins or decals.

Laptop specifications:

Nvidia RTX 4090 Laptop GPU
32GB DDR5 RAM
4TB NVMe SSD (2x 2TB SSDs)
Intel i9-14900HX CPU
Windows 11 24H2 OS

I already tried Community Bug Reports, but the ticket was already canned and blamed on my hardware/drivers, which I’ve already tested and work for literally everything else. It is just War Thunder and whatever is going on with BattleEye.

You can write to support to get help with those types of issues, the bug reporting site is for bugs within the game itself, Support is for other technical issues (like crashes/stuttering etc). You can find support and instructions on how to contact them here: https://support.gaijin.net/hc/en-us/articles/360000262858-How-to-submit-a-support-request

If support can’t help you then i recommend contacting the Battleye support after that.

Are you using Avast as antivirus? Try to uninstall it.

Hey so I had this same issue. I went into the files and went to the properties of the BELauncher config settings file. I right clicked and checked the properties of the file, and it was checked as read only in the General tab. After unchecking this and then going to security and giving every user listed there full control.

Another thing that may have contributed. The Xbox PC version of the game has the Uninstall BattleEye file. I ran that as well after the above mentioned.

So just to trace the steps that worked for me.

  1. Check if the BELauncher config files are checked as read only in properties general
  2. Give BELauncher Full Control in all profiles.
  3. Install the Xbox version of the game (if your version doesn’t have ethe Uninstall BattleEye File) and run that.
  4. Run the game and cross your fingers

Hope this helps!
