You’ll need to reinstall all the plugins for this version of Photoshop separately. (If you go into the pruir version of Photoshop, all the plugins should still be there). I see this happen with the regular and beta versions of Photoshop as well. I’m not sure as to why nothing is showing in the Creative Cloud though. But go ahead and try downloading and re-install the plugins as normal and let me know if you get any error messaages or have any issues
