Data Setup Configuration Error

I’m brand new to Data Looker Studio.

There were Data Looker Studio reports created in my company that were working fine connecting to Google Analytics dataset connector. Suddenly in the last few months they are broken and the data does not pull. It gives errors like Data Set Configuration Error. Looker Studio cannot connect to your data set. I click on see details and a popup window comes up and says “Failed to fetch data from the underlying data set. Error ID: d78140d4”.

My company is using Google Analytics GA4 and has been for about 1 year or more and the reports have been working fine, until recently.

Do I need to upgrade to Google Analytic 4 data set connector? Or is there a workaround for this?
