Hi @JIE LIU
Did you mean that you have removed credentials related to OneDrive and Microsoft 365 apps as the link shown: signed out accounts in Microsoft desktop apps and remove credentials?
If yes, but this issue persists, please try other methods in the link above, such as: Unlink and relink OneDrive.
Besides, you may go to PowerPoint > Options > Save > Click "delete Cached files" for a check.
