**Description:**
Since updating to Build 42 (latest unstable branch), I am experiencing systematic and frequent crashes to desktop with no warning or error message in-game. The game simply closes and returns to Windows instantly. This never happened on Build 41.
The crashes occur randomly — sometimes within seconds of loading into a world, sometimes after a few minutes or more. They are not tied to any specific in-game action.

**What I have already tried:**
- Verified game files via Steam
- Full clean reinstall of the game
- Tested with zero mods active
- Updated GPU drivers, chipset drivers, and BIOS
- Disabled AMD Shader Cache and cleared existing cache
- Forced OpenGL mode via launch options (`-opengl`)
- Tested with Resizable BAR on Auto
- The issue does NOT occur in any other game (tested with Tekken 8, Oblivion Remastered, and others) — this is specific to Project Zomboid B42

**Windows Event Viewer error (consistent across every crash):**
```
Faulting application name: ProjectZomboid64.exe, version: 0.0.0.0
Faulting module name: ntdll.dll, version: 10.0.26100.8328
Exception code: 0xc0000374
Fault offset: 0x0000000000117175
Faulting process ID: variable
Faulting application path: D:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid\ProjectZomboid64.exe
Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll
```
**Exception code 0xc0000374 = heap corruption.** Notably, the fault offset (0x0000000000117175) is identical across every single crash, suggesting this is a fully reproducible code path triggering the corruption.
No `hs_err_pid` file is generated in the Zomboid folder.

**Last lines of the game log before crash:**
```
[07-06-26 21:51:17.742] WARN : General at SpriteConfig.initObjectInfo > Invalid SpriteConfig object! scripted object = Wooden_Windows.
```
(Log ends here with no further error output)

**Additional notes:**
This appears to be specific to the B42 rendering pipeline changes combined with AMD RX 6000 series hardware. Build 41 ran perfectly on this exact same setup with no crashes whatsoever.
Please let me know if you need any additional logs or information. Happy to run any diagnostic you suggest.

So, i tried this yesterday and it seemed to work, i had two long sessions on the game with no crashes, but i just relaunched it (i made sure to check that the services were still disabled) and the game crashed 30 seconds after my save was loaded. Should i keep the services disabled or reactivate them ?
