  • Proton version: 6.3-8

I confirm:

  • [ YES] that I haven't found an existing compatibility report for this game.
  • [ YES] that I have checked whether there are updates for my system available.

Symptoms

I tried to run the game but it only starts/launch on Proton 6.3-8, No other proton version can launch it. I am Vanilla only so i dont have any mods installed. That is the first problem, only one proton version can Launch the game ( we are only at launch no playing yet)

The next problem is that when i start playing a campaign/skirmish/multiplayer ( dont matter same result ) the game crashes it says " Runtime Error! R66025 - Pure Virtual Function Call.

Tried changing the the shaders settings from maximum (default) to high, the result is the game's terrain is black and grey moving constantly like a television without signal thats the terrain.

Tried changing to Low Shader setting, the terrain becomes black hard to differenciate from the obstacles.

please help, i tried changeing proton versions but non really worked. i am on linux mint xfce right now but before i was in Cinnamon linux mint and same problem. so i cant play the game.
