MIssing font in most recent version of MuseScore

I just updated to the latest version of MuseScore (OS: Windows 10 (10.0), Arch.: x86_64, MuseScore ‎version (64-bit): 3.3.4.9066, revision: 7684abe). I have a custom font that I ‎made to display Baroque ornaments etc. It worked fine in the previous version of MuseScore ‎‎(downloaded in mid-November, IIRC; don’t have exact version number). The font is visible in the ‎Windows fonts folder and works properly in every application I have tried — except the new version of ‎MuseScore. When I create or edit staff text and look at the list of fonts available, this font is not shown in ‎the list; somehow MuseScore refuses to use it at all. This is true whether I try to use a text style, edit via ‎the Inspector, or edit directly using the box at the bottom left of the screen. I have restarted Windows, ‎restarted MuseScore, etc. ‎

In the screen shots, you can see the font ‘Baroque Symbols’ in Word’s font list, whereas in MuseScore’s ‎list it is missing; it should be between Balloonist and Basic Sans.‎

Was anything changed in the most recent version that could cause this? Any suggestions? I have a great ‎many hours invested in this project. I suppose I could re-download the previous version, but it would be ‎better to get things working in the current one.‎
