Windows 10: Personal vault - We couldn't unlock your personal vault Error code 0x80070015

On a desktop PC with a fresh installation of Windows 10 with all updates, personal vault works for a few days then I get this error. This has happened previously and is now happening again with a new motherboard/CPU. I can access my vault on my laptop (same version of windows 10) and my android phone without a problem. I can also access my vault on the onedrive website without issue.I have tried de-activating the personal vault and re-activating from the website but the problem always returns.

Personal Vault Will Not Unlock

I received the following error: "Something went wrong with your Personal Vault" and goes on to say "Your personal vault is locked. To access your personal vault please unlock it again." The related code is 0x80316003. I recently installed the Windows 10
home build 1903 a few days ago and enabled the personal vault feature the same day.

Note, I can access Personal Vault via the browser interface but NOT via file explorer.

 

Can't unlock personal vault

I have two PC, one desktop and one laptop both logged in with the same Microsoft account. I've installed Personal Vault on one of the machines (the laptop) but not without difficulty as the install package, that stated it was installing OneDrive for the
first time (when it's been in use for some time) and failed though it hadn't. The Desktop is a different matter. This consistently brings up a dialog box stating "We couldn't unlock you Personal Vault. Something went wrong. Please try again." and the error
code 0x80070015. It then leaves a shortcut in Onedrive that, if clicked, just goes through the above loop. The installation sends me an Approve sign-in request to Authenticator, but it's always the same ID number

I've run SFC /scannow and DISM checkhealth and restorehealth neither of which makes any difference.

Any suggestions as to how to get this working?

OneDrive Personal Vault cannot be unlocked on Windows10.

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.
