See pic above, if I select Never try again. It seems grasshopper block the gha path.
When I put a normal gha input the path with a same name. It also will be not load by grasshopper.
My question is that how can I make this block path name work well again?
No idea but I would look in the GH folder, in some xml there must be that path. Maybe in grasshopper_assemblyhistory.xml or grasshopper_ignorewarnings.xml, look in this folder, and before you change anything without being sure, make a backup. Or maybe you can access from code in Grasshopper.Instances.Settings.
Thank you for your suggestions
I find remove the Test0315.no6 file in the same path with the gha works. Thank you again.
