I have the same problem when I'm trying to refresh reports that are using a Databricks connection or when I'm trying to connect to a new table using Dtabricks connection. Because I've already have the query generated for the existing reports I was able to change the Implementation=2.0 to Implementation=1.0 and is working like this 

Databricks.Catalogs(
            ServerDataBricks,
            PathDataBricks,
            [
                Catalog = CatalogDataBricks,
                Database = null,
                QueryTags = null,
                EnableAutomaticProxyDiscovery = null,
Implementation = "1.0",
                EnableQueryResultDownload="0"
            ]

Hi Everyone, 

I had the same issue on the Jan 2026 release of Power BI Desktop. It looks like the implementation option in the Databricks connection GUI has set itself to 2.0 (beta) automatically. 

Change this to default in the options and this resolved the issue for me.
