Hey there @VerTaTek1! Welcome to the community! This forum is mostly meant for Unreal Engine developers to get help with the engine, but I may have some advice that might help with this. Just keep in mind, much of what I recommend would require access to the source code of the game. As always the first recommendation is a clean install/update of your GPU drivers and disabling any overlays.
Since it seems to be hanging, you may be able to lengthen the time before timeout with a TDI edit:
Alternatively here’s some general GPU based solutions from a different crash that can help limit problems, (though ignore any at that require you to be in engine since you’re unable to do that).
