Description
I just tried to change the font from Menlo to JetBrains Mono, but it caused Qt Creator to crash. I could avoid this crash, by first closing all documents.
Here's the likely most useful bit of the crash report, the full version is attached:

Unfortunately, while previously this crash was happening consistently, I don't seem to be able to reproduce this now, after re-opening the JS file I was editing and some additional C++ files. It might have been caused with a different file, but that list is gone now.
