Description

Issue type

Crash or freeze

Description with steps to reproduce

  3. Remove time signature
  4. Add local time signature (I tested with 6/8) to the first measure (CTRL + mouse drag & drop)

This issue is present since Musescore 2.0.0 (1.3 doesn't support local time signature), probably all Musescore 4 versions are affected too.
