I build time ago, like a year ago an app where owner replaces as required an imported excel file (embedded excel into the app) so it can be use in the app. Yesterday there's been an error "There was a problem deleting your datasource. "More" just show sessionID

At first thought it might be a confussion from PowerApps since it showed me sometimes the Read-Only flag, but when changing to Edit, error remained.
I tried the following:
- Saving as new app.
- Exporting app as package and importing it as new app.
- Restoring a previous app version
None of the previous attempt worked. Other conectors are ok, i can delete them, but the problem is with the import from excel file connector (add static data to your app).
My current workaround was to upload Data (that's my table name) again and PowerApps created as Data_1 so i had to update the connector reference in the formulas from Data to Data_1. That works for now, but can't delete neither Data nor Data_1 and tomorrow I need to update the data again and can't be creating now Data_2 and go on. How can I fix this?
I attach an screenshot of the connector
