I upgraded to WinForms 12.1 and my application is receiving an innerexception error, and I can't seem to track down what it is. Below is my error stack. I was able to get an "Index out of range" message somewhere in the middle of all the exception messages, but not sure where or what index.

Any ideas would be helpful !! 

System.InvalidOperationException was unhandled
  Message="An error occurred creating the form. See Exception.InnerException for details.  The error is: The type initializer for 'InventoryManagement.Main' threw an exception."
  Source="InventoryManagement"
