item with the same key has already been added, export 'StarburstPresto.Contents' is already defined

I upgraded Power BI Desktop yesterday, and I get two errors. One is "The export 'StarburstPresto.Contents' is already defined in this scope.  True," and the other says something like "an item with the same key has already been added."

 
I get these even if I am only attempting to add a blank query or enter table data. I'm not connecting to any data source. I've tried to reinstall, but it has not helped. 
 
Has anyone else encountered this with the November upgrade, and did you resolve it?

I think the update's new Starburst connector created a conflict with the setup I had done months back to allow me to use presto. So I deleted the file I had placed back then (the .mez file at %USER%\Documents\Power BI Desktop\Custom Connectors), and it seems to work now.
