Restored Deleted Project but Getting Error 401: deleted_client

[Avneesh18]

Our project got accidentally deleted from Google Cloud, but we managed to restore it back within an hour. However, even after restoring everything, we are facing ongoing issues with our services. Our users are now getting "Authorization errors" on the Oauth consent screen when trying to use the services properly.

This problem is causing big trouble for our work, and we are trying hard to fix it and make our APIs and services work properly for our users.

Here's what we've done so far:

1. Restored the SureTriggers-Google Sheets project from a backup.
2. Restored the client credentials for the affected project.

Unfortunately, the problem is still there, and we really need your expert help to understand and fix what's causing it.

It would be great if we can get help related to this. We've been unsuccessful in contacting Google Support.
