Error: "Couldn't Open the Workbook"

I have a powerapp that's connected to an excel file stored on OneDrive. When trying to open the excel file online (to add a few columns) I'm getting:


Couldn't Open the Workbook

We're sorry, we couldn't open your workbook. It's possibly corrupt or using a file format that's not supported.


The app is working fine. Why this error and how can I edit the file?
