Im using MPB 13" 2017 and am having this problem since I upgraded to 10.15.4. I have installed every upgrade thereafter (10.15.4 supplement, 10.15.5, and 10.15.5 supplement) but the problem still persists. I tried every solution and workarounds suggested (changing the energy settings, resetting nvram/pram/ smc, booting on safe mode, using different account, used first aid in disk utility to repair the disk, used apple diagnostics to check hardware, reinstalled the macOS, erased disk and clean installed macOS. And still MAC Crashes. I AGAIN erased the disk, reinstalled the macOS clean, and just a while back it crashes. Apple support is now suggesting that it is hardware issue. I am thinking the bugs in Catalina created these defects in hardware. If there's someone there who thinks so, may be we should raise this to apple. It is not fair that we shoulder this unnecessary expenses because of their negligence.

I never took the time to reinstall macOS, I'm too busy at the moment.
I think it is a software issue, it doesn't crash every time so it has to be some weird combination of things happening while the Mac sleeps.
If they don't fix it with this release, I'm afraid we'll have to wait until October with the new macOS major version.

Since 10.15.5 sleeps at 50% battery every time. Battery health monitor doesn’t seem so smart. I hope they have fixed it in this release.

I applied the 10.15.5 supplemental update.

10.15.6 beta 2 showed up (beta 1 didn't), but the "thing" has restarted 3 times with the update not taking hold.

This may be the first Mac OS I completely skip.
I should have skipped, this is a macOS with the most bugs I have used by far and so late into the release cycle ☹️ My MBP is constantly overheating and throttling, even now while writing this comment and I have no other apps open besides Safari.

AND. . . THEN . . . 2 days later the upgrade "took". What is annoying about the whole thing is the
seemingly random nature and the mismatch between when upgrades become available and they can
actually be applied.

I am using a MacBook Air (early 2015). A lot of the time it is on power and connected to an external monitor. Has been rock solid for the 3-4 years I have had it. Held off on updating to Catalina until about a month ago. Now it randomly shuts down when on battery. I need to plug it in to reboot and then the date is wrong and it starts acting weird, windows randomly opening, Office starting up, etc. I reboot and it goes back to normal. It has done this at greater than 50% power, less than 40% and less than 30%. It actually crashed while I was watching the WWDC presentation on Apple Silicon! lol. I have just reset the SMC and Pram and we will see if that helps. It is truly odd behaviour for a machine that has so far worked flawlessly. Trying to hold off on replacing it until next year with an Arm Mac (or whatever they are to be called).
 
Still getting kernel panics on this latest beta. Every few days it will just randomly spin up the fans and shut down. Also restarting quite regularly results in a kernel panic. I really wish Apple would get their house in order before making huge changes to the OS. FFS, please just make it stable.

Do you think they're even going to bother fixing Catalina now? It's been about three weeks now since the last beta release, it's still broken and now their focus will clearly be on Big Sur.
 
I have now gone 7-8 weeks without a Kernel Panic issue since Apple replaced my Logic Board. I no longer have to turn off any of the system preferences listed in many of the posts in this thread (ie. Automatic Graphics Switching, Enable Power Nap, Put Hard Drive to Sleep when Possible, Prevent Computer from Sleeping Automatically when the Display is off). Appears to be a Logic Board Issue with the 2019 16" MacBook Pro.
