photoshop çalışmıyor

In a first step try to reset the preferences of Photoshop using the steps described here:

https://helpx.adobe.com/photoshop/using/preferences.html#reset-preferences

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

https://helpx.adobe.com/photoshop/using/preferences.html#backup-photoshop-preferences

If this doesn't help 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 you're unable to access Preferences and PhotoShop crashes before that, please go to the location C:\Program Files\Adobe\Adobe Photoshop 2026. Then rename the Sniffer.exe to Old.Sniffer.exe and try launching Photohsop again.

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

Take a look especially point 7 in the "Troubleshoot GPU and Graphics driver" section.

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. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.

If this all doesn't help, we need more informations about your system. Maybe you can post your Photoshop system info. In Photoshop goto Help > System Info and hit the copy button. Then paste the entire informations into this thread.

Please read this (in particular the section titled "Supply pertinent information for more timely and effective answers”):

What have you done for all-purpose trouble-shooting so far?
Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:

What have you done so far to troubleshoot the problem? Have you tried restarting the computer, for example?

If you need Photoshop but cannot find a solution and restarting the computer does not work, try downgrading to a previously working version https://helpx.adobe.com/download-install/using/install-previous-version.html
