Try creating a new user profile (keeping the old untouched). I had the same problems on my M1 MBA and assumed complex hardware or OS issues. But all problems are gone on the new profile (still existent on the old one when used). Strange.

On the topic of Hackintoshes: They are becoming more and more obsolet with Apples focus on Apple Silicon, Neural Engines and so on. Not spec or price wise, but regarding feature parity and Apples OS support for the Intel architecture. Lots of old „Hackintoshers“ abandoning the hobby.
