Photoshop 2021 has been dowloaded but won't open properly on Windows 10

I have been using photoshop subscription for a few months now and it was recently updated to the 2021 app.  I have downloaded and installed and have been able to launch but I can't open files or anything else.  I don't get any error code, the program just doesn't do anything.  I am also subscribed to Bridge but have never been able to get it to work.  The strange thing is that if I go to my control panel and open programs and features in the list that comes up I see PS 2021, 2 Photoshop 2020l's, and 1 photoshop 2019.  I have tried to uninstall but the message comes up that these programs are not on my system.  Please help.
