OneDrive Personal Vault cannot be unlocked on Windows10.

I was able to get rid of the Red X on my OneDrive icon and the error message saying that the Personal Vault could not be synchronized by doing the following:

1. Access the personal vault OnLine via the the View OnLine option from the desktop icon in the task bar.
   
2. Open the vault via the Web Browser and select all the files and folders in the vault.
3. Count all the files and folders presently in the Personal Vault.
4. Move all the files and folders out of the Personal Vault to another folder in your OneDrive.
5. Refresh and verify the Personal Vault is empty.
6. Verify all your important files have been successfully moved by verifying the folder and file count.
7. Disable the Personal Vault online via the Web browser.
8. Select the Personal Vault and attempt to delete it. A message "Cant delete Personal Vault' appears.
9. Click on 'Go to settings'.
10. Select the options to Disable the Personal Vault <Select Disable>. and "Disable" when asked are you sure. [NOTE: when you do this, any contents in the vault are irretrievably lost. So make sure it is empty first.]
11. Wait 30-60 seconds for your OneDrive desktop to synch.
12. Go back to the browser and select Enable on the Persona Vault window if it is still opened.
13. If you closed the window, select Settings in the upper right of online OneDrive (to the left of the question mark), select options, select Personal Vault from the left side menu, then select Enable.
14. A pop-up stating, "Your Personal Vault is back". Select 'got it'.
15. Click on OneDrive in the upper left corner of the browser screen.
16. Find your Personal Vault in your file/folder list.
17. Open it (you will have to authenticate to open).
18. Inspect the vault. It should be empty. In some cases there will be old "uncached" files that appears. It was the failed synching that caused the Red X. Reestablishing the Personal Vault allows the synch to proceed. Be careful as these files might not
    contain the most contemporaneous data.
19. You should now be able to use the Personal Vault as before without the Red X. You can move the files you moved out of the Personal Vault back into the Personal Vault - - begin careful to decide which version to keep of any duplicate files.

I recently enabled the Personal Vault function in OneDrive (Office365 + 1TB subscription).

The vault functions correctly via browser and on my iPhone/iPad.

However, it doesn't work on my Windows10. I get two warning windows saying:

"Something went wrong with your Personal Vault.

Your Personal Vault is locked. To access your Personal Vault, please unlock it again.

[Unlock] [Close]"

And:

"We couldn't unlock your Personal Vault.

Something went wrong. Please try again.

Error Code: 0x80004005.

[OK]"

To save you time, yes I have all updates installed, rebooted my PC twice, logged out of OneDrive then logged back in.
