Hi Tony Huang1
Thank you for using Microsoft products and posting them to the community.
I realize that you have encountered a Onedrive issue.
Thank you very much for your detailed description of the problem. You are a very good user, you are really great, you have carefully discovered and described the full picture of the problem in detail.
We have received feedback from some users that the issue has been fixed and can be accessed normally, so we recommend that you try opening the Personal Vault again in OneDrive.live.com or File Explorer to see if it can be opened successfully.
Whether the issue is resolved or still exists, please reply to share your experience with us and help us understand the latest progress of this issue.
Best regards.
