This happens to me only on this score:

  1. Export to mp3
  2. Deselect "normalize"
  3. MuseScore will crash in the process of making the mp3, leaving a corrupted file

As exporting won't touch the to be exported file, that can't get corrupt.
Or what am I missing here?

Also I can't reproduce this, the MP3 export just works

Same. It only happens with big, multi-instrument files for me: Musescore 4 crashes, the MSCZ gets lost and I just managed to recover it through opening the MSCX in musescore 3, then re-saving it there as MSCZ. I think my problematic MSCZ file is somehow corrupted, as I can't save it as any other format, export it in any other file type... don't know what would fix this though. I really hope this gets resolved. Musescore 4 is an amazing achievement, but the fear of entirely losing hours of work is super scary.
