I just upgraded to Unity 6000.0.20. The Input System is at 1.11.0. I’m now seeing the following exception when I select an item from a drop down menu…

MissingReferenceException: The object of type 'UnityEngine.GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Any idea why this is happening? None of my code has changed and the exception isn’t very illuminating, since my code isn’t referenced. I’m guessing this is a bug, but I’m not certain.

I downgraded to Input System 1.10.0 and the problem went away. I’m going to submit a bug report.

  2. Close Unity
  3. Remove Library folder
  4. Open Unity

I tried that. It didn’t work. Same exceptions.

It’s already been reported and fixed in an upcoming release: InputSystem 1.11.0 throw error when destroy canvas

Some code got through that should not have made it past review.
