I tested [this](https://gitlab.com/chir-set/RcHacks7/-/blob/900664b75fca04210a065f1324d7fae0214eb559/14-UndoRedo.py.txt) implementation that _derives_ from the [original](https://projectweek.na-mic.org/PW39_2023_Montreal/Projects/UndoRedo/) work you linked and did not observe any crash in the scenario you described. May be you could give it a try.
