@insta360_support I really don't think I have deleted it, as when I open Premiere and then open the Stitcher Importer it still works.
It isn't in the path you've listed. When I search for this text string it doesn't find anything. But it still loads in Premiere, and Premiere is still slow and laggy.
Any other ideas where it might be so I don't have to do a completely new Adobe install?
