Hold down the Shift key and launch Photoshop. A dialog appears during launch that reads “Skip loading optional and third-party plug-ins?”
Skip the 3rd party plugins and try to launch.
Also did you tried resetting preferences?
I just tried opening Photoshop while holding the shift key,
did not succeed .. it still froze while showing the spinning beach ball with the dialog box you mentioned
Resetting the photoshop preferences you mean,
just tried that while holding Option+Command+Shift keys
Did not work also, again.. it froze while showing the spinning beach ball with the dialog box
Anyone other options??
Since you mentioned that resetting the preferences did not help, did you try uninstalling Creative Cloud and reinstalling the same?
Feel free to reply back in case you continue to face the same issue.
I finally ended up getting hold of the (Indian) Adobe telephone team
Polite guy by the way
He first told me that he thought that the problem was that photoshop would not work with one of the two standard graphic cards that I had
That felt unlikely somehow because otherwise thousands of Mac users worldwide would have problems with working on Adobe CC?
It in the end turned out that if I made a new Mac user, and then opened Photoshop from that new user account, it did work
So somehow my Photoshop did not work with my old useraccount.. strange
a corrupted file maybe?
by now it is working again
