Yes, we recommend using Photoshop 22.2 if you continue to need access to Photoshop 3D features.
The download process is very simple, but we will walk you through it step by step just in case.
Log in to your Creative Cloud account and select the "Apps" option on the left. Locate the Photoshop application and click the three dots below the tile.
Select "Other versions" and scroll down through the different versions of Photoshop until you find version 22.2.
Click it and... that's it! Done.
Sure! You can easily install the current version and 22.2 or whatever 22.x version you prefer, and switch back and forth between versions
