That somehow resembles what I‘m experiencing: rock stable for days or even weeks, with no problems when sleeping/waking the machine and automatic display sleep enabled; then, all of a sudden I get back to the machine having KP‘d and shut itself down. After that I most likely get additional KPs shortly after (either the WindowServer one or a CPU CATERR), after which the machine is likely to be stable again for several days.
No clue as to what is really going on here...
OK. But you say you don’t see the Kernel Panic (watchdog timeout) discussed in this thread?
You might be on to something here.

Maybe you have some hardware trouble with the Mac mini and/or the RX580? Difficult to say. But maybe it's software. ?♂️
Still, I don't really have any stability problems while using Catalina (on RX 5700XT). It's mostly upon wake from sleep for me. One or twice during boot too I think. I don't know how many times I've written that in this thread now.

RX580 via eGPU connected?

Someone said it helped to install the combo update on top of the existing installation. I doubt it, but can be worth a try:yes. I think the problem described below persist:
Apple's macOS Catalina causing problems with select eGPU setups | AppleInsider
Despite overall feature and performance improvements for external GPUs, the new macOS Catalina is now failing to work correctly with certain combinations of Mac and GPU card.

Good to know. I recently bought a 2020 Macbook Air Quad-Core Intel Core i7. I hope that it doesn't have this issue. When did you start seeing this issue? My machine is only 1 week old.
After about a week or two. Tried everything. Finally took to genius bar, sent off for repair
Do you put it to sleep and wake it often?
I do sleep/wake fairly often. I'm not sure on the rest, I just got it in July, so had Catalina already installed. It's my first MBA, always wanted one. Had an iPad pro 9.7" before that.
Will be interesting to hear how it goes – good luck!

I'm suspecting it might be related to graphic drivers for (some of?) those AMD cards, but I'm mostly guessing here, so could be wrong.

I don't have any suggestions other than hoping Big Sur (that might released tomorrow) will help on the issue. ?
