Steam/Windows 11] Random Unity crashes – Player.log shows BrotliDecoderIsFinished

Hello,

I am experiencing random Unity crashes in the Steam version of Gems of War on Windows 11.

System:

  • HP Pavilion Laptop 16-ag0xxx
  • AMD Ryzen 5 8540U
  • AMD Radeon 740M
  • 16 GB RAM
  • Windows 11 Home 24H2 (Build 26200)
  • Steam version of Gems of War
    The problem:

The game randomly crashes after I have been playing for some time. It can happen both during active gameplay and when the game is simply left open without playing.

I also have a separate problem: sometimes the mouse stops responding to the game board. The game itself remains open, but I cannot interact with the board. Closing and restarting the game fixes it temporarily.

What I have already tried:

  • Steam file integrity check: 3164/3164 files successfully verified
  • Steam Overlay was disabled previously — the problem remained
  • -force-glcore — the problem eventually returned
  • -force-d3d11 — the game now definitely runs using Direct3D 11, but the crashes still occur
  • Windows Hardware-accelerated GPU Scheduling (HAGS) — disabled, but this did not solve the problem
    The crash log shows:

Forcing GfxDevice: Direct3D 11

and the crash occurs in GameAssembly.dll, with:

BrotliDecoderIsFinished

The log also shows a large unloading of unused Unity assets shortly before the crash.

I am attaching my latest Player.log.

Could you please take a look at the log and let me know whether this is a known Unity/Steam issue or whether there is anything specific you would like me to test?

Thank you.
