KeyNotFoundException: The given key was not present in the dictionary.

i have no Idea what is going on. It was working perfectly fine then I added a few more achievements and now i get the error. Please help I've spent hours on this problem and I'm really not sure what to do at this point.

It only lets me instantiate the first 11 on load. Also It starts with the Achievement Menu active, rather than waiting for input "I" before opening.

Thank you all for your time!
