I figured out that you actually can use Photoshop CS6 still on Catalina with a bit of sneakiness!
Go to the Photoshop app, right click, view contents, open MacOS folder and double click on the terminal file labeled Adobe PhotoShop CS6. It opened for me with no issues and I'm using it just fine :3 It will still not open from the regular way through the application itself, but at least I don't need a new version, phew! I had a near heart attack when I read these threads after my OS updated lol so glad I got it working! Hope this helps you guys too!
