Crash in Creality Print/Windows

Easy to duplicate crash in Creality Print for Windows.

  1. Add a model. Doesn’t seem to matter what type, but I tested with 3mf and stl.
  2. Use the “Others” - “Drill” tool to add a hole to your model. Add more holes at different angles/faces.
  3. Use Ctrl-Z to undo the addition of the holes. Repeat.

About 50% of the time I can get it to crash during one of the undos.

There is a 4.3.9 beta available on github, might be worth testing to see if the issue persists in the newer version.
