Hello @GabrielZucchi,

Welcome back to the AppSheet Community! I did som research on similar cases and I found there is a possibility that for some reason AppSheet can’t connect to your data source. Probably a table has been renamed, deleted, or you have lost access/permissions. Please check the following:

1. Check Table Permissions: Ensure the data source hasn’t been deleted, and that the account you are using has full access/viewing permissions.
2. Re-authenticate Data Sources: Go to Account > Sources in AppSheet, and reconnect/re-authorize the account that hosts your data.
3. Regenerate the Table Structure: In the AppSheet Editor, go to Data > Tables, click on the table causing the error, and select Regenerate. This refreshes the connection and updates any modified column structures.

5. Check App Plan Status: If the app recently stopped working, check if your subscription plan is sufficient, as unpaid or expired plans can block app definition access.

Another possibility include performance issues, you can find further information here:

With thousands of files, this becomes a bottlenec…

Let me know if this helps please.
