Ladybug install ghpython error

hi i wanted to install Ladybug during the installation i got this error here.

Windows10, Rhino 7 installed
I try to fix the issue and downloaded the newest Grasshopper Components as Functions GHA of GHPython. The Problem is no icon showed up in Grasshopper and cant find it in the subcategory math :confused: some one know the issue and can help me?

I founded the solution it is below in case anyone else has this issue.

Basically, uninstall Rhino and reinstall the program. This should fix the issue.

Or use the Pollination Grasshopper single-click installer that also installs the LBT plugins for you, as well as Radiance and OpenStudio.
