Musescore Studio crashes when adding certain things after a multimeasure rest.

Issue type

Crash or freeze

Description with steps to reproduce

Open any score.
Enable multimeasure rests.
Insert multiple measures at the end of the score using any method. Cmd-B, inserting multiple at once witht the add menu, and copying and pasting empty measures all work.
Open the Barlines menu on the left and click any option. The application crashes.

Barlines are not the only feature that causes this crash; it appears to happen with most features that are attached to a specific measure and cannot be moved. This includes barlines, clefs, key and time signatures, and some repeats. Repeats that cause this crash include regular repeat barlines and Fine, but not measure repeats or first/second endings.

macOS Sonoma 14.4.1

Additional context

Tempo changes, dynamics, and text do not cause this crash. The crash also does not occur if something on the score is changed after the measures are added, even if that change is undone (for example, adding and then removing system text).
