I'm sorry but I'm new to Musescore, have little experience with code, and I don't understand how to implement this fix or how to update with the correct code. Is there a source you could point me to that explains how to utilize this fix? Or do I just wait for the next release? I've been searching around but haven't found anything that I understand.

Please wait, the PR has not yet been merged into the code for the next update.
Fixed in branch 3.x, commit bd8b029c9c
_fix #310869: crash on DPI change in preferences
Resolves: https://musescore.org/en/node/310869
The crash is a null pointer dereference.
We are processing a spin box but referencing a combo box.
This appear to me to have been a copy/paste error.
It belongs to the combo box clause above._
