Some fonts I installed on Windows 11 were suddenly not showing up in SOME apps even though they were visible in the system fonts list and in other apps they did appear...So i went to check the file to see if there was anything weird about it and spotted this checkbox so I thought hmm okay and checked it
And that gave me an error which I didn't screenshot and can't make happen again but it said, and I quote "Too many posts were made to a semaphore"
WHAT THE FUCK DOES THAT MEAN
Well I did just "fix" it by installing them for all users. I did not come any closer to understanding the actual problem
