We're sorry about the trouble with Photoshop. Would you mind telling us which macOS version are ou working on?
You can try disabling the option to Use Graphics Processor from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.
If the issue persists, please re-enable the option to Use Graphics processor & go to Technology Previews under Preferences. Then enable the option to Deactivate Native Canvas & relaunch Photoshop to check if that helps.
