Symptoms

Starting the game and loading a savegame/scenario works completely fine, the game works without issues.
But the moment I close the savegame/scenario and reload back into the same, or another savegame/scenario the game crashes. This issue was already existing in Proton 9.
It appears that something points to nothing during the reload (Line 25857 to 25876):

Unhandled exception: page fault on execute access to 0x00000000 in wow64 32-bit code (0x00000000).
