I agree seems like a driver problem but since nobody else seems to have the same problem, I'm not sure. I haven't tried the nouveau drivers but I have tried the nvidia-drivers with the kernel-open flag set and it didn't seem to change anything. Interestingly I did check the dmsg and here is the output from when i start the game until it crashes :
[ 92.303974] nvidia_uvm: module uses symbols nvUvmInterfaceDisableAccessCntr from proprietary module nvidia, inheriting taint.
[ 92.329270] nvidia-uvm: Loaded the UVM driver, major device number 511.
[ 92.610831] Disabled but requested by user space. You should enable Landlock at boot time:
