Same problem. Brand new 2021 MBP M1 max, 12.2.1. Ran Premiere Pro in January and edited a 15 minute long 4K wedding video without issue. Just yesterday Logic Pro became unusable. Crackling started suddenly and seemed to get exponentially worse with every playback, even if just listening to a single recorded track at a time. Turned off “set date and time automatically” in System Preferences like someone a few posts up suggested and it seems to be resolved. For now. Unacceptable by Apple that we are a year into thread with no answer from them.
