Photoshop Icon on my MacPro dock shows a question mark and does not open
Does anybody know what is going on? I have Photoshop 2021 installed in my Mac Pro (iOS Catalina), running well until this very moment. I dragged a picture onto the icon at the dock, and a ghost question mark appeared on top of the icon and nothing happened. I opened Creative Cloud and my Photoshop was there, and I opened it throught Creative Cloud. Is it going to be like this from now on???
PLEASE HELP!
Thanks in advance!
P.S. I looked for the Photshop app in the big list of apps in the lower part of Creative Cloud and it was NOT there. I could only see it on the top part, where it said Photoshop was up to date.
