Same problem here with a brand new MBP2021 14 M1 Pro. I'm very disappointed. I was using a MBP2015 13, and it was reliable, the reason why so many musicians like macOS.
After trying a lot of tricks (safe mode, relaunch of coreaudio, setting audio rate to 48kHz...etc.), I finally found one that seems to work on my computer: Switching off “Set date and time automatically” in System Preferences.

Hope it will help some. But hey, Apple, WTF?!?
