CC 2019 Welcome Screen loading forever

I try to load PP and the Welcome Screen is blank with a loading circle continually spinning in the middle but nothing happens.  On the top left of the welcome screen box it shows %CCX_START_PANEL_NAME.   I've attempted uninstalling/reinstalling....Adobe Creative Cloud Cleaner Tool, and nothing.  I've searched forums, have done the whole "hold alt/shift" while loading to reset preferences..and still nothing. Any help will be appreciated,
