Hi there, i had the same problem, plus my "Preferences" was greyed out. I got on a web chat with Adobe, and it was only then that I realised that I hadn't updated the Creative Cloud App. It was asking for an update, but I had been ignoring it. The reason for this was that I've got older versions of Photoshop and Bridge installed because the latest versions were too buggy. When I saw "Update available" I thought it was going to update Photoshop and Bridge.
Anyway, after updating the Creative Cloud App everything is back to normal. I can see my apps, the updates that are available, and the "Preferences" is not greyed out.
Just for information, the latest version of the Creative Cloud App is 126.96.36.1991
Maybe this could be helpful to someone having the same issue. My system language (and desktop cc app) differs from the language I used on the installed apps, and somehow the setting in the preference menu of prefered language for the apps went back to default, so basically when I changed that back to the language that I used on the installed apps they automatically shown up again.
