Here is the output of the launch_game.sh script for additional context: launch_game.log

I close this report, as the crash is not reproduced with the last update, and open a new one, for I am still unable to launch the game.

I noticed an update of shaderapix11.so. I guess it has been fixed. There is no mention of it in the changelog.
