Can't activate fonts on multiple desktops (MacStudio M1)

Hi,
Seems like I have the exact same issue as this : Fresh Mac install, can't activate fonts - #11 by mready8991 Unfortunately, this seems like it was unresolved.

Since then, I tried on one of the workstation to launch FontBase with full disk access, it didn’t work after a few seconds.
Then I tried with a connection to my own phone 5G hotspot, so it was not on the organisation network, and it still failed.

I’m out of idea and can’t get why this works fine on my computer but not others, even similar one.
