Final Cut Pro hangs while validating audio units

When starting Final Cut Pro, it hangs while validating audio units. Logic Pro validates them OK. Reinstalled FCP and MacOS. What next ?

Yes, it's boring since a lot of years that it's not able to disable AU scan in Final Cut. I personally don't need any audio plugins in FCP.

At now it hangs here :


Please fixit very soon! I can't use FC at the moment.
