In general, most of the authentication issues that involves the integration to Google (Spreadsheet, Drive or App) were resolved by other users by doing the re-integration process.
That is by removing first the integration, save the form, and then re-integrate.
Make sure to remove first any integration.
Hope this help. Let us know if issue persist.
