There is an error reported when trying to load the symbols for the crash log.


However, it doesn't crash when using 3.0.0. The debug log just shows:

INFO: Could not find files for the given pattern(s).
WARN (bke.anim_sys): C:\blender-git\blender\source\blender\blenkernel\intern\anim_sys.c:3472 BKE_animsys_eval_driver: invalid driver - grease_pencil_modifiers["Thickness"].thickness[0]
