Hello @Johnny_Hacking, sorry to hear about this, have you tried different browsers already?
This might be helpful as well: Unable to connect to Google drive - #14 by Scott_Burns
And in case this does not help have a look here also Export Live Data from Asana into Google Sheet - #3 by lpb although that seems to be only for the project and not portfolio level.
If your Asana plan has also stayed the same and the troubleshooting does not help I recommend reaching out to Asana support as I am sure they will be able in having this resolved
