Short description of error
EXCEPTION_ACCESS_VIOLATION - appears after I call script inside blender from command line. Command "bpy.ops.object.add_fracture_cell_objects" causing error. I tested 2.8, 2.81, 2.82, 2.83, 2.9 with same result. Everything works fine within Blender.

Exact steps for others to reproduce the error
I attached whole testing enviroment. Run test.bat to reproduce error. It runs simple py script which runs scripts "SceneScript" inside Blender.

It seems Blender is drawing windows even if it is executing in background mode if an operator explicitly requests a redraw, which I guess shouldn't happen.
