Photoshop automatically creates a rectangle when opening.

hello,

unfortunately i tried this and many other methods. i tried my own trial and error methods that are not here but it didn't work. sometimes the white screen doesn't come until the application or the working window opens but then it definitely comes and the whole photoshop freezes. when it didn't solve the problem i finally formatted the computer. this solved the problem.

Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?

Do you use the Homescreen?
