Hi, sorry about that
I don’t have a solution, but maybe if you try to reset the preferences will work, here the instructions:

Another option: install a previous version of Photoshop
Go to the creative cloud app and click on the 3 dots next to Photoshop app to see more options and select other versions you can install a previous version of Photoshop and maybe that will work, sometimes there are bugs and you have to update the system
Let me know if that works
Also
you may try the Creative Cloud Cleaner Tool to remove the existing app installation & reinstall once done.
