MuseScore 3.6 crashes when rearranging instrument positions and changing Ordering (see description)
1) Create a new score and use one of the Orderings. I used Orchestral. You can use any instruments.
2a) After the score is made, press I (go to the Instruments list) and try to move one of the instruments around (esp. outside of its natural grouping, e.g. moving a Violin out of the String section).
2b) Also try changing the Ordering.
3) More often than not, it crashes on either one of these actions.
Since this happens with a completely new score, I have not uploaded any specific score. As you can see in the "Reproducibility" field, this is entirely random. I have done 2a and 2b multiple times and sometimes it works and sometimes it crashes. I can't see any real pattern.
