Power Query - New UI previews default query, blocking UI

Hi,

I haven’t found a setting that turns off the preview for the first query. The editor opens on whichever query is at the top of the list, so the simplest workaround is to put a lightweight query there. A blank query or a small parameter table works, and you can drag it to the top.

I’d also check File > Options > Query Editor, and under Current File > Data Load, try toggling “Allow data previews to download in the background”. The effect varies by build, so test it both ways.

If it only started after an update, rolling back is worth a try.

If this helped, feel free to give it a kudos or mark it as solution, helps others find it too.
