Personal Vault OneDrive Error Code 0x80070015
You encountered the error 0x80070015 when trying to open OneDrive Personal Vault in File Explorer. Microsoft asked for your OneDrive and Windows version, then promised an update but closed the case without a fix. You've reset, uninstalled, reinstalled, disabled and reenabled OneDrive, ran virus scans and system checks, but nothing resolved the issue.
I suspect Windows 20H2 could be the issue, while your other machine with Windows 1903 functions properly.
