Changing to a custom font doesn't work reliably

[datamuc]

Windows Terminal version

1.21.2701.0

Windows build number

10.0.22631.4317

Other Software

No response

Steps to reproduce

• Install custom font like "Fira Mono" or "IBM Plex Mono"
• Try to configure it in Windows Terminal

Expected Behavior

I expect the font to be changed

Actual Behavior

Windows Temrinal claims in cannot find the font when pressing the save button. This also happens if I change the font directly in the JSON, as soon as the config file is saved Terminal says it cannot find the font.

Although, after I trigger something (I did not find out yet what it is, maybe it's just randomly, it suddenly works until i restart terminal again)
