Adobe CC 2019 stuck on welcome screen
I've just updated my apps to the 2019 version of Creative Cloud, and I just started to see problems. When the app is opening, welcome screen is getting stuck, it's not loading anyway. I already tried to uninstall all my previous installations, run Adobe CC Cleaner, restarted my windows a lot of times, and then after installing adobe Creative Cloud app again and Illustrator, bingo, start screen is loading forever and ever.
See the image below, that's the only thing I see when I click to open Illustrator, but also is happening to Photoshop too.

Is that a bug or my windows installation could be corrupted? And, for the 2nd case, why the 2018 version was working fine?
