This hasn't been my experience at all. I'm running a hackintosh of all things on vanilla x86 hardware and I haven't had a kernel panic for months (and even then the only thing I can think of was when I was screwing with something that's supposed be behind the curtain). Importantly, I'm more and more resolute against installing Catalina.
Then you probably have a hardware defect somewhere
I had maybe one or two kernel panics since OS 10.1 more than 15 years ago, even with hackintoshes or water damaged MacBooks, so that would be a real shame if that’s due to Catalina and it’s not a hardware problem.
