Hi and thanks for reaching out. My name is Jan. I'm an Onedrive Advisor and a user like you. I'll be happy to help you out today. I want to apologize if you encountered this issue. I understand you have a problem with your computer not working properly.
Please try to reset your Onedrive app.
-Press Windows key and R.
-Type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press OK.
If this error message pops "Windows can't found..."
type this instead:
C:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /reset
and press OK.
Then restart your PC then try to open Onedrive again.
