Crash on opening with a file saved in previous versions of Musescore

[mercuree]

Issue type

Crash or freeze

Description with steps to reproduce

Opening the file Londres_Suite_2_duet_arci.zip crashes Musescore 4.6.0 master.

• It may take several attempts. Crash does not always happen.
• Crash is believed to be linked to voltas and hidden staff
• I can't reproduce from scratch this state where voltas can be present in a staff other than top staff, so I assume that the file was originally created in previous versions of Musescore (maybe 4.1 or 4.2)
• No crash in Musescore 4.4.4

What is the latest version of MuseScore Studio where this issue is present?

MuseScore Studio version (64-bit): 4.6.0-250540307, revision: github-musescore-musescore-9033dc2

Regression

Yes, this used to work in a previous version of MuseScore 4.x

Operating system

Since there is no crash in 4.4.4, I think I misspelled that it is MS4 regression. It should be regression nightly.
