Game crashing everytime after reloading world - pls help - [linux mint 20.2]

Hey,

I have problems running the game stable, after following a few of the recommendations from the game website but i seem to hit a wall here.

I run the game with the mesa_glthread=true

mesa_glthread=true bash run.sh 

After that it worked an i played about an hour without any problems regarding performance. The next evening and every time after that i have problem loading my savegame.

Running a new savegame works, but doing that every session kind of ruins the game!

I hope somebody can help me.

This is the error I get after trying to load a savegame:
