Help needed: War Thunder crashes on Intel HD 4400 - Heavy Cavalry update

Hello everyone,

I need technical help. Since the Heavy Cavalry update,
War Thunder crashes immediately when any match starts

  • even Test Flight.

My specs:

  • Dell Latitude E5440
  • Intel HD 4400 (integrated GPU)
  • 12GB RAM
  • Zorin OS (Linux) / Ubuntu 24.04
  • Mesa 25.2.8
  • War Thunder 2.55.1

What I have already tried:
✖ All graphics set to minimum/ultralow
✖ Shadows, clouds, sky disabled in config.blk
✖ renderer changed to OpenGL
✖ Shader cache cleared
✖ Full reinstall
✖ Minimal client (22.5GB)
✖ TLP disabled
✖ fpsLimit set to 30

Game crashes the moment match loads.
No error in terminal except MESA Vulkan warning.

Has anyone with Intel integrated graphics
found a fix for Heavy Cavalry update?

Any help is appreciated. o7
