We're sorry about the trouble with Photoshop. Would you mind sharing the version of Photoshop you're using?
Please go to the System Preferences for your Mac, then Security and Privacy, then select the Privacy tab. Then select Accessibility from the list to the left and check if you see Photoshop added to the list with a check mark in front of it. If Photoshop is not a part of the list, please add it by unlocking the window first using the lock at the bottom left, then clicking the + icon and navigating to the Applications folder. Also, grant permissions to Photoshop under Full disk access located in the same list as Accessibility. Once done, restart the Mac and check if it helps.
