Hi,
Did this problem only appear in specific PowerPoint?
Can you upload the file through web directly?
Where did you open the file? From local or cloud?
I suggest you try to reset OneDrive:
- Press the Windows key + R and open the Run Window, enter:
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
- After few minutes restart OneDrive, you can enter:
%localappdata%\Microsoft\OneDrive\onedrive.exe
Please provide more information about the problem and I'm glad to help you.
