How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.

 

Disabling sign in screen

Thanks for the suggestion. I am getting an error: "The user name or password is incorrect. Try again." I think this could be due to an issue with having two user logins with the same name. I get two options on the sign-in screen on the bottom left of the screen, both say Jon Lawrance. See attached.
