Plasma 6 landed in opensuse. However, I recommend to do it in tty because if you do it in plasma the upgrade will be incomplete because the shell will crash in the middle of update without installing all. In case this happen to anyone, just reinstall plasma 6 pattern and it will go without problems
So I’ve updated my desktop and Plasma, Nvidia, and Wayland is actually usable 🫨 but I had to reapply a few settings.
