Can't see my uploaded pictures

Hi there; would appreciate any help.  It's been a year since I used Capture One 20 for a Mac, due to Covid...anyway, I started a new session (tried multiple times), I fill in the regular information, try to upload my pictures out of a folder or card and nothing happens...I don't see the pictures.  Makes no sense to me and retired a dozen ways on looked online for videos as it's been a while - if anyone has any advice would sure help...thanks.
