Error - Oh Sheet! . Maybe too many tabs


I have an app that I want to duplicate, but I get the Error - Oh Sheet! I am the app´s author.

Maybe is that it times out because it has many tabs. I am going to see how can I downsize the spreadsheet, Regards.

Check for empty rows or columns too. Remove as much unnecessary data, rows and columns as possible.

I have removed empty rows and columns, as well as all formatting and some of the tabs, but still nothing. I am going to start the duplicate with the other Glide user from scratch.
