Text Font ignored by MuseScore v4.0 but works perfectly in v3.6.2 and all other applications.

A font that I rely on is accessible in every application that I use except for MuseScore v4.0. I've attached a side-by-side comparison between the old and new, with the font highlighted in blue.

I've reinstalled the font, uninstalled then reinstalled MuseScore v4.0, restarted the PC (many times), but to no avail. I can't get v4.0 to recognize it.

I'd love some thoughts and suggestions as to what might be causing this and how to overcome it. Thank you.
