My MacBook started crashing randomly after the last update. The screensaver and power saving is off, and the reboots happen if applications are open, or they are closed and it is just sitting idle.
MacBook Pro 13", macOS 10.15
I have 2 Mac's both 2015's. The only way I found to solve the crash is to install Catalina via a bootable USB. Once I restored from Time Machine the crashes came back. One of them doesn't have Norton, the other does, but both would crash out of the blue. It was pain, but I copied all my files off, installed Catalina from scratch, reinstalled my apps, copied my documents back over and no crashes, not even the Norton installed one crashes. I have a feeling the upgrade has issues, not sure if they are security related, or files not updating, but hopefully they will fix it on the next round.
The Ultimate Solution doesn't working.
I have MBP16 and after upgrade to 10.15.4 I had terrible random crashes.
The only solution worked for me is downgrade to 10.15.3, after that I don't have any crashes.

Inform Apple of the Fix you Came Across:
Most certainly, provide that fix as feedback to Apple. That way, they can be made aware such a fix.
To Report the Bug’s Fix to Apple:
Until they fix it, stop letting the hard-drive go to sleep. Use the work-around. Sleep the screen during the day, shut them down at night, set the "Open All Previous Windows" option for the next boot time.
Nothing can be done until there is a fix AND since there is a viable workaround, it kinda lowers the priority on a rush. Add to that, all of their engineering and support resources are strained due to the virus.
So, save yourself some time and grief, use the work-around...
Updated to 10.15.5 yesterday. Left laptop in sleep for the night and it didn't crash for the first night since I got it. Haven't yet tried the same with peripherals connected. Will post my update here if it crashes again.
Also updated to 10.15.5 yesterday (MBP 16"). Multiple times letting computer go to sleep and waking without crashes/shutdowns/issues. Let got to sleep on own last night and woke without problem. Running with 2 external monitors and a Seagate thunderbolt external hard drive.
Fingers crossed!
So, I've just turned off 'Enable Power Nap' under Energy Saver with the external monitors plugged in. It started the screen saver and didn't freeze. See how this goes.
This DEFINITELY has nothing to do with Norton. I don’t have Norton, never had it, never used it, and my 16” 2019 MacBook Pro crashes almost every night after being idle. I worked with Apple 1st Level Support last week, ran hardware diagnostics - CLEAN. I reinstalled macOS 10.15.4 from Recovery mode. Also reset NVRAM/PRAM and SMC. None of this made a difference. Within a day or two, crashing returned.
This is DEFINITELY an underlying problem with 10.15.4. Gouging to reopen the case with APple Support today and see if I can get this issue escalated.

Provide Apple Feedback on this.
The more they hear of this, the more they’ll know what is going on, and what needs to be included in the next updates.
Apple Feedback Site:
Save your energy, been there, done that. To ALL that's having this problem, here's what I've already done with my 16" 2019 MacBook Pro to troubleshoot/resolve this issue:
1.) Checked Disk Drive via Disk Utility First Aid (from Recovery Partition)
2.) Reinstalled macOS from Recovery Partition
3.) Worked with Apple 1st-line support, ran hardware diagnostics (all components pass)
4.) Reset SMC and PRAM/NVRAM
5.) Total erase of drive and re-install of macOS. Recovered data from backup and manually re-installed my Apps
6.) Upgraded macOS 10.15.4 With Supplemental Update released within last 24 hours
I did these things, in the order listed, and still the idle-screensaver-reboot issue reoccured. My conclusion - This problem is rooted in the bowels of the 10.15.4 update. It is NOT triggered by any single App or hardware component (ex. I use a 4K and 5K LG Monitors connected to MacBook, along with 2 external 2T disk drives for storage and backup).
On phone now with Apple Senior Tech Advisor. WIll update this post with results.
As a follow up on my post, I removed Norton on April 4 after my post, then restarted the computer. Since then it hasn't crashed once or restarted at all.
As I mentioned, I'm in Mojave, so this could well be a separate problem for me, but I'd gotten here with the same error message, which makes me suspect a software problem. I'd held off on updating only because of my Fujitsu scanner, which I love and which had super buggy software with the upgrade to the 64 bit version. Please keep us updated with the Catalina upgrade issues.
I am running a mac Pro 10 core with 16GB Vram and 128 gb ram. I have had random crashes under 10.15.3 and was hoping 10.15.4 would fix it but it seems to make the problem worse. Before I was having crashes while working, all video would freeze, but the system would run for a minute before restarting. Now under 10.15.4 my machine is crashing when the Screen saver starts. I tried unplugging 2 external monitors and the screen saver came on with no crashes. Am i too suspect that the external monitors are causing an issue? Is it to do with graphics drivers and metal? Before I had the machine running under 10:15:3 for 2 weeks max when I stopped using the Speaker port after reading something about audio drivers, but it then crashes 6 times in 2 hours. It seems to be when the screen saver started. Could it be sleep mode with external screens?
macOS 10.15.5 just released this evening. Release notes indicate they fixed a wake-from-sleep problem with MBPs connected to external displays. Perhaps too it solves our crashing while sleep issue.
I’ll be upgrading and testing tomorrow to see if it works. Will report back soon.,.
Exactly my symptoms too.
Annoyingly, it went from happening 10x a day to not happening at all for about 6 days, but it's started again now.
I uninstalled iStatMenus yesterday and it hasn't restarted since, but given the intermittent nature of this, I don't know if this is an indicator or not. I'm on 10.5.5. Fairly certain this started happening at 10.5.4.
Your issue does not sound like it belongs in this thread. This thread was about auto-reboots due to wake-from-sleep issues. Has nothing to do with Firefox or any other App.
If your Mac doesn’t automatically notify you of the 10.15.5 update, then you can go int System Preferences and initiate the update procedure yourself. If your Mac is running any earlier version of Catalina, then it should locate the update.
Have you run any "cleaning", "optimizing" or "speed-up" apps?
