when i open an excel file that i created i get below error even though i set myself the permission

”you are not signed in office with an account that has permission to open this workbook. you may sign in a new account info OFFICE that has permission or request permission the content owner”

I am signed in with  correct account with a license. 

No issues accessing other files, only one file with issue.

Made no changes so confused why its an issue. One night working fine, next morning i have this issue.

File looks to be corrupted after speaking to chat support so how do i fix this?
