I can't confirm, but I wonder if somehow this might not just affect templates, because I had another crash and I don't know if I changed its location.

It was the same log though, I think.

I wonder if it's related to the actual contents of your desktop? Is this totally reproducible for you using that folder? What if you choose a different one - and empty one, perhaps?

Marc, I tried a new, empty folder called test, and I couldn't reproduce.

EDIT: After some more testing, I think it's because MuseScore doesn't like if there's a subfolder.

Thanks for the continued investigation. That was the clue I needed. Indeed, I got it crash just by adding an empty subfolder called "subfolder" to my empty Templates folder. The crash happens at the start of ScoreBrowser::setScores(), on the first line "qDeleteAll(scoreLists)". scoreLists appears to have trashed, not sure how. I'll let someone else investigate from here...
