Kicking me out

My shaper keeps dropping out! Now when I try to open said drawing it will just drop out again. Why is this happening?? I’ve tried restarting and closing out ect. No change. Help!

Probably the drawing (or the model itself is too complicated or has some sort of messed up topology. You could try opening it on a computer with better capabilities, but normally, that shouldn‘t happen. Can you / or is it even an option to delete the drawing? Maybe that would solve it. If you can, just make sure to duplicate the whole project before it.
