Short description of error
Crashes when undo/ redo enters and exits different modes; tested with object and edit mode on default startup file and consistently crashes.
Exact steps for others to reproduce the error
- select default cube and press (tab) several times to cycle modes from object to edit mode (3-4 times or more)
- undo shortcut (ctrl z) several times (3-4 times or more causes crash)
- redo shortcut (ctrl shift z) crashes blender (always crashes on the 3rd or 4th redo on my system)
Based on the default 2.83.1 and 2.9 startup files; tested on 2.82 with 256 undo/ redo steps without any crashes.
