Hello Shoeb,
Are you able to access it on the Web version at https://onedrive.live.com page?
If so, let me suggest an OD Reset:
Press Windows+R keys on the keyboard, or Right-click Start on the Taskbar and choose Run.
Paste C:\Program Files\Microsoft OneDrive\Onedrive.exe /reset
Press Enter.
Sign in again and verify.
I look forward to hearing from you to get the results of the troubleshooting.
