TRUETYPE FONT DOESN'T WORK

Good morning. I've been having problems with a tablature source for recorder for a long time. I was asked to detail the problem with pictures, etc. This is extremely difficult because when I use the font it is not shown. There's no way for me to show details: she just doesn't appreciate it. However, it is enough for the Musescore programmer to install this font to verify the error. So I will upload the font as a zip file. I know I don't contribute financially to Musescore but I really miss this source and I save a lot of time editing my methods. See in the attached images what happens in Musescore 3.6 and Musescore 4.0.2. Please help me. Thanks!
