Argument out of range - 2 year old project
Receiving an Argument out of range exception for a 2 year old project that has never thrown this before. I simply highlight my mouse over a Unity UI element and it throws the error.
Unity 2018.4.17f1
Note that I'm able to highlight other UI elements and start the game (even mess with credits). If I resume play it continues like before without issue.
The only thing that I can think of that has changed is that I tried copying the folder to a new location on a separate drive, but I've since gone back to the original project location once this showed up.
I have tried adjusting my layout, as this shows up as a way to resolve it in older posts
Should I delete any meta data associated with this object to try and refresh it?

Whew, solved it. I had forgotten I tried adding a new script to the button to fade it, but never really finished the script so it was throwing the error. Simply removing this fixed the issue. I got to the solution by slowing rebuilding the button to see what broke.
I do wish the error was not so vague and actually pointed to the problem...but whatever, time to update my game on Steam.
