Logic Pro X crashes with Fireface UC

I use Logic Pro X and a Fireface UC. From one to the other

day quits Logic (does not respond) as soon as I connect the Fireface UC via USB. the system always ran flawlessly. When I connect the USB to the

Remove the USB from my Interface RME Fireface UC Logic X works completely again

normal. Unfortunately, I can't figure out why Logic x is after the

connection of the Fireface UC interface adopted.

Logic is up to date, Fireface UC is also newly installed

with the last driver and USB settings firmware v126, driver v3.24.

I also dated Big Sur, none of which led to a solution

my problem. I also had the problem with the IOS Catalina. How

I said I got the problem overnight without any having made or automatic update or something like that, i.e. a change of the system.

just before i downloaded Reaper to have a test with that DAW, all good, it works with my interface Fireface UC.

need help pls...

Thank you!!!
