We can't "get Data" or refresh exsisting data in PowerBI Desktop. Moreover, if I published the pudated pbix file to the cloud. The refresh on the cloud failed as well.
While the same file can be open, refresh and get data from BigQuery normally with PowerBI Aug-2020.

Similar problem here. The existing tables in my model connected to Bigquery do not update any longer on Power BI Desktop and I can't connect to new datasets. The only difference is that the files are being updated just fine on the cloud version.
