What I think is going on, is for some reason, in Silicon M1/2/3 macs the command set is corrupted, it does not affect Intel machines, only the Silicon M macs...
What I have found is pressing command + [plus] key when in command set mode in Final Cut Pro, it changes the command set from German to English, but the change is non permanent... let go of a key and it goes back to German.
