unable to IMPORT Photos

I have done the same Importing Process for over 10 years. 

When I click “IMPORT” after I have ensure File Handling, Collection Location, etc.  The status bar in the top left appears as if it were to be “working” on importing with the status bar on the top left of the LrC window; building Smart Previews, applying my Presets etc.  Then, NOTHING. When I try to repeat the process and I click on “IMPORT” again on the bottom left of the window; the folder doesn’t pop up to find the Photos, Create a Collection Location, etc. It’s as if LrC has froze. I have been trying multiple times; deleting the App and reInstalling it. Creating a New Catalog as well, and even in the new catalog LrC does the same thing as far as “working”, then nothing.
