I have the same issue, but I don't see the debug screen after the failure and it happens less frequently. Today the computer crashed after 22 hours, while being in standby mode. Usually it then restarts into the login screen of the previous user. The problem appeared only after I upgraded to Catalina.
Configuration:
MacBook Pro (13-inch, Mid 2012), RAM 18 GB 1600 MHz DDR3
Laptop is connected to power and battery is full.
Library/LaunchDemons: com.apple.installer.osmessagetracing.plist and two plist from com.philandro.anydesk. Nothing else in LaunchDemons or LaunchAgents
In the Preferences are additionally Fuse and GPG Suite.
Otherwise no apps running. (not even from Apple)
I recently upgraded to 10.15.4 - no improvement. The Mac still restarts itself. (But additionally the OS now forgets my keyboard layout when I need to enter the password after restart.)
I don't have that problem on my MacBook Air with the same software configuration.
It's really not easy to do work on my Mac while the OS is that unreliable. A fix would be greatly appreciated!
