Musescore 4.4 crashes when trying to insert one measure at the end

In this score, when I go to the latest measure, try to insert a new measure at the end (with ctrl + b), Musescore crashes.

I can read the following in the terminal (where I run musescore4portable)

06:37:00.940 | INFO  | main_thread     | ActionsDispatcher::dispatch | try call action: append-measure
/tmp/.mount_musescU3mq54/AppRun: line 29: 182581 Segmentation fault      (core dumped) "${APPDIR}/bin/mscore4portable" "$@"

When I try to copy-n-paste one measure at the end (after adding one measure before the latest measure with Ins), it crashed also with the terminal showing:

This is really annoying since I can't finish my work on this score.

Thanks for your support,
