come to ask again about load KarambaIDEA

hi, i try to regenerate the KarambaIDEA GHA files,
and i get it (now sure whether it really works)

and the situation is

the first time visual studio open rhino, then rhino add grasshopper development fold,
then open grasshoppper,
the grasshopper seem dead when load at 87%

then I use window task close rhino, reopen rhino and grasshoper,
it says something is not load. the grasshopper is open.

then I load this example files, then it looks different , something is missing.


I dont know how to do then, and where problem is , pls help
