Kernel panic issues- getting worse

Hello.

My Mac tends to shutdown from kernel panics and is worse when updating software and upgrading operating systems. I attempted to install OS Catalina and ended up having to restore my system from an old Time Machine backup. I downloaded EtrePro and pasted the results. I've tried to remove all of my AVG software, but it appears there are still some kernel extensions messing up my system.
