Aloha kakou,
I’m just getting started in ArcGIS Pro by following along a Udemy course. When I click Catalog in ArcGis Pro’s start page, it sort of freezes. When I hover over the program icon in the task bar (encircled in red in screenshot below),

I see it has “tried” to open a new project, however, it does not appear:

I’m sure it’s some simple remedy but restarting my computer didn’t fix it.
Many thanks,
cyrus
