The Given Key cannot be found in the Dictionary and I have no idea why. Worked perfectly before.

I am getting the error of:

 KeyNotFoundException: The given key was not present in the dictionary.
 System.Collections.Generic.Dictionary`2[TKey,TValue].get_Item (TKey key) (at <437ba245d8404784b9fbab9b439ac908>:0)
 numberlist.Update () (at Assets/Scripts/numberlist.cs:87)
 

I've been looking up information on this error but I don't know how the other questions can apply to my code. The weird thing is, this code was working perfectly and then one day I open up Unity and it's no longer working. I don't think I changed anything.

The code for this is below. I updated Unity recently, maybe there was a change in there? I'm so confused. If anyone can help, thank you so so so so so so so so so much! ^u^
