Fear That Clock is Ticking on Texture Effects

I use and depend on Texture Effects for making promotional photos and posters for theaters. I have had to jump through a few hoops lately just to use it and I’m afraid that soon it will no longer work at all with my new Mac Studio. I realize that it is discontinued but hopefully some of the features might be carried over into some new apps that will save me from trying to figure out how to find a replacement. Thanks!
