On Windows it doesn't crash in 3.6.2 nor in 4.4.2, but it does crash in 3.7, when starting playback. It seems related to a) the score having hidden staves )no crash woth those unhidden) and b) to the extra voltas on the 2nd staff, the stack trace hints at there being an issue. See https://github.com/Jojo-Schmitz/MuseScore/pull/647 for an attempt to fix that.
