Cannot Connect to Google Big Query Data Source

When trying to connect to a Google Big Query data source using the native connector, some of our users are getting the following error: 

This seems to have started with the October update to PBI desktop. 

Other things we know:

• We are able to connect to GCP with the user specified in the authentication process, with no issue.
• The error happens either using the "recent sources" path to connect, or trying to establish a new connection.
• We have tried deleting any cached connections to Big Query and started from step one. This did not resolve the issue. 
• We experience this on older and brand new .pbix files.
• The error happens to some users, but not others. We are a large enterprise where PBI versions are managed. Accordingly we should all be on the same PBI version, build, etc. 
• This used to work without issue; 
• Installing a local ODBC driver to work around this, is not an option (see statement about large enterprise, managed machines, etc.) 

This is a significant risk/blocker item for us as connection issues to our primary data platform (Big Query) would potentially stop any further expansion of PBI use. Any assistance would be greatly appreciated.
