Hi there,
Sorry that Photoshop 22.2 is running extreamely slow on your computer.
Does the app freezes while performing a specific task? What is your computer's operating system? To get started, you may checkout the steps mentioned here: https://helpx.adobe.com/photoshop/kb/photoshop-slow-lags.html
Also, would you mind deselecting the option "Use Graphics Processor" located in Photoshop's Preferences > Performance menu, then relaunch Photoshop and let us know if it helps?
Thanks,
Akash
