Is using the null-conditional operator ?. sufficient to prevent this exception when dealing with GameObject ?

Seems like someone did an oopsie there. The ? operator should not be used with UnityEngine.Object types because of the fake null handling.

Hello,

@MaskedMouse has right propagation null propagation operator are not compatible with GameObject(cf UNT0008).
This bug has already been reported ISXB-1081 and the fix will be included in the next release.

Thanks for reporting it.

This isn’t the best fix, will make OnPointerEnter events invoke repeatedly.

Unity’s fix works better, code is here: FIX: ISXB-1081 Fixed "MissingReferenceException" errors when closing … · Unity-Technologies/InputSystem@008f573 · GitHub
