Error: panic(cpu 0 caller 0xffffff8009ea2d1c): Sleep transition timed out

I didn't assume anything about what type of Mac you had. Not possible since you haven't said. I was only pointing out the very few search returns I could even find on this error mentioned Hackintosh and Catalina on unsupported Macs for more than half of the return results.

Reporting to Apple, as you noted, doesn't do much good since reports do not get answered. They get sent to the appropriate department and that's pretty much it.

Have you called Apple's technical support line, or brought your Mac to an Apple Store to be evaluated?
