Pick and Paint extension was updated to be compatible with Slicer-4.11 and these changes were not compatible with Slicer-4.10 anymore. I’ve now updated the extension index to use the old version for Slicer-4.10 and the current version for Slicer-4.11.

You can use Pick and Paint extension in Slicer-4.11 now. If you reinstall Pick and Paint extension in Slicer-4.10 tomorrow then it should work, too.
