i have a toolbox in my project that refuses to go away. it is a duplicate of the correct toolbox, it is invalid, it has a date with the year 1600 (pretty sure Esri wasn't around then), and i cannot delete it.
the problem is that when i go to make a new project package in the share tab i run analyze and it gives me an error because of this toolbox so i cannot create package.
help me delete this thing.
