Behavior

Deleting a box shape which has a cylinder negative volume attached causes an error. After the error is closed, PrusaSlicer crashes.

To reproduce:

• right click build plate> add shape> box
• right click box > add negative volume > cylinder
• click on the box in the right side object list to select ONLY the box (deselect the negative volume cylinder)
• trying to delete only the box will produce error (From Object List You can't delete the last solid part from object)
• click OK or close on the error message > crashes here

Interestingly, the crash doesn't seem to happen if you use, for example, a box shape with a box negative volume - the error will pop up as expected, but PrusaSlicer will not crash. Sorry, I did not test more combinations of boxes and cylinders and modfiers, but box shape with cylinder negative volume will reproduce a crash.

I forgot to report this, I experienced it too. It seems to happen any time you try to delete the parent model before deleting the children. (Except, perhaps maybe the exception you stated. Maybe same shape doesn't crash.)
