iMac running Catalina having shutdown problems and constantly restarts

I see some old posts relating to this which sound similar issue but can't see any solutions. Does anyone have advice? Hangs on shutdown, often seems that it is ok but next morning I find it has restarted and asks to send an error message to Apple which I have done on multiple occasions. Can't see what the problem is. Check everything has shut down - only thing running in background is a WD HD which time machine uses for back ups.

Starting to really annoy me

iMac with Retina 5K display, macOS 10.15

Thanks Leroy

I have downloaded and run it now and have the full report after allowing full disk access - although I see it says it was disabled here so not sure why that is. I can see it's not a happy machine which I kind of knew. To my knowledge there is no antivirus now installed so that's a worry. I'll try to shutdown and restart and run again before posting the report in the hope that it might go to full disk access that way
