We're sorry about the experience with Photoshop. The way you've described the issue it appears that Photoshop is crashing on launch. Would you mind telling us which version of Photoshop are you using along with your computers operating system? Could you check if you're able to access the Preferences of Photoshop? If you are, please try disabling the option to Use Graphics Processor from Photoshop by going to Preferences, then Performance.
If you're unable to access the Preferences through Photoshop, you can try to reset the preferences of Photoshop manually using the steps mentioned here: https://adobe.ly/2Qzc0K3
