We are not using Copilot at my place of employment so I' not sure why there seems to be an interoperability issue with Copilot. I am able to dismiss that error and use Power BI Desktop but I'm also experiencing another issue. If I try to sort a column by another column in the same table (in this case sorting a spelled out Month column by a numeric Month Number column), I get this error (I guess I can't paste a picture in a comment so hopefully this is enough: Feedback Type: Frown (Error) Release: February 2026 Product Version: 2.151.1052.0 (26.02)+f24ef72a680490da641de392ea586cef1b10bfc8 (x64) Error Message: Cannot perform interop call to: ModelingServiceHostService.ExecuteDataQueries(args:1) - wrong arg[0]=dataQueries value { "queries": [ { "canSortByColumn": { "column": "modelobject://Table/Date/Column/Month", "sortByColumn": "modelobject://Table/Date/Column/Month%20Number", "tablePartitionMode": "Import" } } ] } Co-workers can open the same pbix file and perform this sort with no issues so this seems to be unique to me or my machine. I uninstalled and did a fresh install of Power BI Desktop and that did not resolve the issue.
