    Many users have reported running into this issue. It seems to happen when multiple different accounts are used to sign in to OneDrive or Microsoft services in the same browser session. For example, this can occur if one account is signed in to Edge, while another account is also signed in through a different Edge tab or an InPrivate window.

    To avoid this, try keeping each account in a separate browser. For example, use Edge for one account and Google Chrome for another. This helps prevent account session conflicts and may stop the error from appearing.
