New install of ArcGIS Pro, Windows 11. Start project with blank template. Want to add existing folder, so in Catalog pane/folders, I right-click, select AddFolder. UI pane starts, but update stops and Error reporting tool pops up. No recovery. It 'appears' that I can't use existing data.
Hints on how to fix?
In this particular instance, I resorted to a Windows refresh/repair. Then reinstalled ArcGIS Pro. Runs beautifully now.
