Fonts are missing

Operating system version Mac Monterey 12.5.1
FontBase version 2.17.5

I’ve copied all my fonts into the Users/UserName/Fontbase folder

The folder now has 5383 font files in it .ttf and .otf

When I open Font Base there are 3887 fonts

I’ve tried manually adding the fonts I need but they just don’t show up

Hello @Mayk, thank you for your post and welcome to the forum, and sorry to hear you’re having issues with the app.
To help us understand what the cause of the issue might be, what happens when you’re adding the missing fonts manually?
Thank you,
