Hi @Kaur, Jaspreet ,
How did you open the file? Did you open the Workbook from OneDrive?
Did this problem only appear in specific file?
Is this a shared file from other user?
First try to check if the account is login successfully, you can sign out and re-sign in.
Then check if the file is expired.
You can also refer to this support article and check if you can get any information from it:
