Is Catalina stable? Crash often?

My 2018 Mac Mini is stable with Catalina but make sure you check your software first to make sure you do not have any 32-bit software you need to run. You may run into some issues with Music (missing cover art, etc) and TV app.

2018 Macbook Pro, no crash whatsoever yet. Not even a hiccup. It works perfectly.
The only flaw, if I can call it that, is that it scrambled my apps in the Launchpad. But that's something that every major macOS version does; it has become a tradition.
 
Just crashed on me. Does anyone know how to decipher a crash log to determine what is wrong?

Code: 
panic(cpu 8 caller 0xffffff7f9faebad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 140 seconds
service: com.apple.logd, total successful checkins since wake (39370 seconds ago): 3938, last successful checkin: 0 seconds ago
service: com.apple.WindowServer, total successful checkins since wake (39370 seconds ago): 3914, last successful checkin: 140 seconds ago

Man, I'm having the same problems as you on my 2019 iMac. I called Apple support and they told me to do NVRAM reset, SMC reset, and then a clean install. Same problem persists. I've now totally given up and I'm just gonna wait it out. I already spent like 12 hours trying to find out what's going on.

2019 iMac. Had kernel panics every day, I did a clean install and I'm having more kernel panics somehow. Apple support asked me to do a bunch of things but so far no solution.

Thank you! Sorry, I find it very frustrating but I am glad I am not the only one. I am just about ready to call it quits and go back to Mojave. Nothing worked from Apple Support for me either. Hopefully they are getting a lot of reports on the 2019 iMac systems and have an update planned.
 
I myself have not updated, but a good friend of mine is having a lot of issues with it on his 2013 iMac. He's dealt with a few crashes, a lot of slowness, and a few small issues with third party apps. He also had a strange issue with the music app, he let it play overnight and when he woke up, the app had closed. No error message or anything, it just wasn't there anymore.
