Photoshop is broken. I can't use the program properly.

Unfortunately you haven't given us any information about your system. Therefore, all proposed solutions are a look into the crystal ball.

Please try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

If it helps, you can check out the steps suggested here:  https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html

If the issue persists, you can try to reset the preferences of Photoshop using the steps described here:

Please backup your settings before resetting the preferences. You can check:

Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. Please make also sure that you have installed the Studio version and not the Game Ready version of your NVidia driver.
