I work with files that are 1 1/2 years old. I come back to these files. But the more updates follow one another, the more Photoshop - now 2022 (before it was CS) - struggles to work. Do I need to uninstall the application and then reinstall it to solve this handicap?
If your system does not meet the system requirements for PS 2022 and is struggling, then you can uninstall it and install the previous version using the Creative Cloud app. You can also turn off automatic updates.
