I just updated Rhino 8.8.24170.13001. When I opened Grasshopper, the loading errors box appeared. After clicking close, Grassshopper can be opened. But I just want to solve the loading errors that appear every time.
I found the bug is Tunny Plug-in that is not compatible with Rhino 8

Thanks for the report.
I am a developer for Tunny.
Sorry for putting in a bug that affects the whole of Grasshopper.
This issue is due to the compatibility of Tunny configuration files being lost between Rhino7 and Rhino8.
The fix is to delete Settings.json in [UserProfile]/.tunny_env.
