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

I have already said I eliminated hardware being the issue but I am including my specs here

here are my gnome extensions I tried removing some extensions I'll add the word del in front of the extensions I removed.

On top of the errors in the logs above, I am now getting the fail whale error:

gnome-session-binary: 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 happened 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?

Please disable Secure Boot.

Should that not resolve the issue, see the solutions at PKCS Signature error/warnings running dmesg on Ubuntu Mate 18.04 which involve removing all references to NVIDIA drivers, then re-downloading version 367.27 and reinstalling it.

Should all else fails, LWN.NET has patches to resolve the PKCS#7 issue.

From the comments...

You've got WAY too many GNOME Shell extensions. As I said in my first comment, one OR MORE are giving you your problems. You also have duplicate extensions in /usr/share/gnome-shell/extensions that shouldn't be there... all by the same author.

The way to troubleshoot this is to temporarily disable ALL extensions at , and remove the dups at /usr/share/gnome-shell/extensions, and run for a few days and see if things stabilize.

After determining a base line, enable one extension at a time, and test some more. Any problems that arise may be due to the last extension that you enabled.

Reduce the total number of GNOME Shell extensions. You really don't need/want them all.

Last thought... if you've overclocked your CPU or RAM, disable that.
