Windows 10: Error "Something Went Wrong" when attempting to Sign in to Account From Any Device Won't...

First of all, I have looked at the other similar problems posted, but they all refer to an application specific or device specific error that can be fixed with reboot/signing in from another device. My problem persists across all devices phones, tablets, laptops, phones with data-> not connected through personal wifi. It arose after I was attempting to dual boot my windows 11 computer with linux, and the linux installation required space analysis, which Windows wouldn't allow due to BitLocker encryption being on. However when I went back to turn off BitLocker encryption, it required my re

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?

• You do not have a data connection.
• Your phone is in a "bad state."

We suggest that you follow the steps on this link to set up your Microsoft

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.
