Looker Studio cannot connect to your data set.

[Annica]

I have some reports in Looker studio who worked fine, and I haven't change a thing but suddenly I get this error: "The data source no longer has access to the underlying data set. Please contact the data source owner to fix it.".

I have connected Google analytics multiple times, but nothing seems to work. Is anyone familiar with this issue who could help me fix it?
