I tried again on a MacBook Air M1 and I didn't succeed to make it crash. There could be something else (3D view size? File size?).
Not sure why you'd offer detached 3D view if you don't think people should use it.
Are you sure that kind of comment will help? 
By the way, you're the first one to report this issue that I tried to fix immediately. Don't ask too much!
