Short description of error

Blender crashes when performing Undo with Load UI disabled

Exact steps for others to reproduce the error

CrashTest.blend

Open Blender
Reset to factory settings (File - Defaults - Load Factory Settings)
In Preferences, turn off Load UI (Save & Load section)
Click "Save Preferences"
Open the file CrashTest.blend
Perform any action in the scene (I rotated the camera)
Perform Undo (Ctrl-Z)
Observe crash

Note! If I clear the scene, I can perform any action and undo it without a crash. For example I created a cube, rotated it and performed an undo without a problem.

There were some fixes for the new undo, and I can't recreate this here. Even with various memory utilities enabled (that should aggressively check for and detect any memory issues, which are typically the cause of such crashes).

Could you test with a newer 2.83 and if that doesn't work, a 2.90 build? https://builder.blender.org/download/

Tested with the latest 2.90 (1f1520a045) and it works fine. No crash.

I managed to recreate this bug also in 2.90 (1f1520a045). Might warrant a reopening.

Open Blender
Reset to factory settings (File - Defaults - Load Factory Settings)
In Preferences, turn off Load UI (Save & Load section)
Click "Save Preferences"
Open the file CrashTest.blend
Perform any action in the scene (I rotated the camera)
Perform Undo (Ctrl-Z)
Observe crash
