Over the past month, Ubuntu 18.04 occasionally freezes. My mouse will be free but I can’t click on anything or even use Alt+F2 for a command. I usually follow these directions to restart my system with the REISUB method (and I’ve also changed the permissions the way the user described). Whenever I rebooted the system I didn’t look at the crash report but today I opened
var/crash and found
linux-image-5.4.0-47-generic.34291.crash that contained the following:

I’m running Ubuntu 18.04.5.
I’m not sure where to go from here so any help in the right direction would be much appreciated.
