Consistent BSOD due to BEDaisy.sys (BattleEye)

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.
