We're sorry about the trouble with Photoshop. If you're getting an error while trying to launch Photoshop or while trying to open an image in Photoshop, would you mind telling us what the error says? Which operating system are you working on?
You can try disabling the option to Use Graphics processor from Photoshop 2021 by going to the Preferences, then Performance. Once done, quit & relaunch Photoshop to check if it helps.
