18.04 - gnome-shell freezes and then after a minute crashes

I have been having a lot of issues with Ubuntu such as hangs, crashes, refuses to load my account etc. I have eliminated hardware being the issue as I have checked all my hardware. Some of these issues were fixed by trying different combinations of kernel versions and bios versions. But I still have some gnome-shell crashes that I can't fix. Checking my logs reveals a lot of error messages I don't know how many of them or normal. I will attach 2 logs one from gnome-logs google drive to log 1 with only important events showed and another google drive to log 2from journal showing all that plus warnings

on top of the errors in the logs above, I am now getting the fail whale error gnome-session-b: CRITICAL: We failed, but the fail whale is dead. Sorry....

Update: now Ubuntu won't boot at all I just get a black screen with a mouse

Update: okay I got the system to boot but it's a 50/50 chance it will boot from a reboot a full shutdown and then power up seems to work but now all my chrome based browsers won't open websites, Firefox works fine though and another new issue I can't launch steam

Update: ok so I seemed to finally get most things under control no more secureboot related errors. I guess its been a combination of updating to the 5.3.6 kernel and reinstalling my Nvidia drivers and removing some extensions anyway, I found out the gnome-shell freeze is due to a memory leak in gnome as I checked when the freeze happed gnome would be using 5GB of ram. I am also still randomly getting stuck in the Plymouth boot logo maybe I should just uninstall it?
