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

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:
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.
Uninstall the Symantec software according to the developer's instructions and run for a while to see if there's any improvement.
There's no reason to run any "cleaning", "optimizing", "speed-up" or anti-virus apps on a Mac. They are unnecessary. If you have any other than Symantec download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

I'm getting the same error message, but I'm in Mojave (10.14.6). This crash has been happening off and on for the past couple of months. This is an iMac I got this past August, so barely six months old, and it's been doing this for at least half that time.
I do have Norton running on it, so it might be a Norton issue for me. It seems to restart a lot overnight. When it restarts when I'm using it, it's happened most often when I'm searching for something in Spotlight or using the search feature trying to track down an email in the Mac Mail. It just blinks out in a scary way, like someone pulled the plug.

"April 9, 2020: Got notification of update to original 10.15.4. On restart, system stops installing software. I waited about 45 minutes, then unplugged computer. Plugged it back in and computer came up. I am getting notice to install the software update but will not. If system updates on its own, I'll follow same procedure."

Create a New Administrator:
Try creating a new administrator to perform this install. If it work with the new administrator, then transfer everything over to the new user, and then trash this current user. You should be good to go from there.
Then Try a Manual Download:
Go Here: Download macOS Catalina 10.15.4 Supplemental Update - Apple Support. Connect this directly into your router using Ethernet, if an available option to you. Elsewise, use Wi-Fi.
Important: Download it from Apple and none other. Elsewise, it may be a scam, or malware.

Seems providing feedback is was great. As, in turn, Apple to created a fix. On the 8th, this was released: Catalina 10.15.4 Supplemental Update. This update with be included in the reinstallation, which may fix this update issue.
Important: Backup your Mac First, with a Time Machine Backup.

No -- but if it is new, then perform Send-In Service:
Right now, with the Coronavirus Pandemic going around, mail-in service is available. You have a one-year limited-warranty. So, contact Apple Support. You will be shipped a box; you'd ship the Mac in via box; Apple will fix what need be; and Apple will send it back to you. If a faulty device, service will be free of charge.

”[...]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:
Update to 10.15.5 went smoothly. Left machine on overnight, reset to the "Put Hard Disk To Sleep" option in System Preferences, it went to sleep, woke up normally WITHOUT incident! First time since before 10.15.4 was installed. Also, all peripherals woke-up instantly, without sputtering or delay, which I think somehow contributed to the earlier crashing. In the 10.15.5 Release Notes, they specifically state they did something to fix awake problem with external displays connected.
Going to run several more tests thru Sunday and if no failures, will declare this bug fixed in my mind.
MACHINE: MacBook Pro 16" (16 GB RAM, Core i7)
DEVICE CONNECTIONS:
day two update, so my new logic board came with 10.15.1, so i bravely updated to 10.15.5. so far so good, Except with chrome !! with GPU acceleration enable in chrome, some websites are corrupted with lines !! yet another problem, ! perhaps i should have stayed with 10.15.1
its only a few sites, other people with MPB 16 have reported this, the solution is to turn off GPU acceleration in chrome !!
anyone else seen this, ?
My bet is on Norton, but Logitech has released some crappy kernel extensions in the past.
Start by uninstalling Norton AV following the developer's instructions or uninstaller.
Norton doesn't provide anything but problems.
Same issue, since the 10.15.4 update. My MacBook Pro (16") has rebooted 4 times in past 10 days since upgrade, usually after sitting idle for several minutes/hours.
prior to the upgrade, unexpected reboot "might" have occurred twice since I bought this laptop a few months ago.
My MAC PC has been locking in the morning following recent update Catalina 10.15.4. Cannot get rid of spinning circle until I unplug system and allow it to rest. Turn back on and allow it to come up. Had to do this twice today. Is there a solution.
