If any of the above techniques allows Photoshop to run: Try updating your video card drivers. See Photoshop CC graphics processor troubleshooting guide and FAQ for more information.

Run Photoshop in a new user account

You can experience application crashes if your user account is damaged, or if your user account lacks rights to files and folders that your Adobe application requires.

Start the Adobe application in a new user account: Create a user account that has the same permissions as the account that you use when the problem occurs. If the problem doesn't recur, then the original user account is probably damaged.

For more information, see Create a user account.

Start Photoshop in an administrator account: Create a user account, and change the account type to administrator. (If you do not have rights to create an administrator account, contact your system administrator.) If the problem doesn't recur, your standard user account lacks access rights to files and folders that Photoshop requires. 

Verify that your user account has access rights to the following folders:

• C:\Users\[User Name]\AppData\Roaming
• C:\Users\[User Name]\AppData\Local

For instructions, see Log in using built in-administrator | Create local administrator account.

Run Photoshop in Safe Mode

See the document Safe Mode with networking to reduce the probability of any issues with drivers, third-party services, or anti-virus programs.
