I searched for the closest thing I could find to “release notes” and found Version History on the Dorico update download page. I searched the forum for “preference” and “delete.” Sorry for my denseness, but neither turned up anything about specific preference files to delete to solve the empty Media Browser issue. However, after deleting most of the Dorico preferences I could find in my file system, I got some greyed-out, unselectable lists in the Halion Media Browser. The list disappeared again from the Media Browser if I clicked the back button on the filter, and I was unable to get the list back until I restarted Dorico. I’ve attached images that show the files I deleted before restart (The selected ones are those I deleted.), and an image of the greyed-out list.
