MacBookPro crashing after Catalina upgrade on wake up

Ever since I upgraded by MacBookPro to Catalina the OS kernel panics and crashes. When I close the lid at work, arrive home an hour later and reopen the laptop I find the OS has rebooted and the usual crash report dialog prompts up when I log in. Below is the the crash log.

Any ideas help to debug or solve would be appreciated.

This is 100% reproducible. I'm new to Mac debugging, please let me know any more info required.

MacBook Pro 13", macOS 10.15

Avast anti-Virus software is causing you nothing but issues—look for the official in app Un-installer.

Hi Leroydouglas,

I'm still getting crashes and very reproducible now. It seems to be due to the external monitor being unplugged just before going to sleep (on lid close) or after going to sleep. I think it can't gather all the desktops back onto the main laptop screen because at one point quickly reconnecting the external monitor after repopening the list worked but next few times it didn't.

I have 5 crash logs and latest is attached.

Looks like the Windowing system or the display driver needs some work.

Any ideas?

Hello,, still having issues I'm afraid on my side. I would hold off upgrading if you haven't already. Seems to be related to the external monitor being unplugged.

I would try re-installing the macOS on top of your existing macOS to sort this. This will leave your user files in place, refreshing the macOS.

I did this after the first few crashes and it didn't help.

Definitely a problem with the external display being unplugged. I believe the driver doesn't check the HDMI has been unplugged when the USB-C HDMI adapter is unplugged....

Probably a good idea to remove it before installing. It will save you some hassle. These are the instructions I used;
