generic-serializable-dictionary: InvalidOperationException: EnsureRunningOnMainThread can only be called from the main thread

Hi, I get this error when working with your class. Until now it works fine, and I can’t see where is the problem (I mean, I think I commented all the last changes before the error appears but still keep there…). Do you think there is some solution in your class? Here is the full stack error. Thank you.
