Thank you.

I have 4 virtual desktops at the moment.
But it does not work on my set up.

Is qt6-quick3d installed?

That did for me! I installed qt6-quick3d, then restarted Plasma 6 and now the cube works! Thanks!  Why is this not being installed as a dependency?

On arch linux kde-unstable, it is listed as an optional dependency of kdeplasma-addons:
qt6-quick3d: desktop cube effect [installed]

Installing qt6-quick3d solved the issue for me too.

Thanks!
