Need help with Argument Exception

i got this error when click on Animator, please help me

 

please, anyone help me

 

Do you have no animations in it, by any chance?

 

i created all animation, it just happened recently and i don't know why

 

Your animator controller's busted.

I've seen this happen before! I sent a bug report, and it got accepted. Haven't heard anything back since.

Essentially, I got it from dragging a sub state machine to the layer above itself, where a sub state machine had the same name. That caused two machines to have the same name, which the animator doesn't handle.

You can fix it by opening your animator controller in a text editor. There will probably be two AnimatorStateMachine or AnimatorState entries with the same value for m_Name. Change one of them, and Unity should be able to handle it again.

Edit: hey, I found the bug report video I sent to Unity. Testing in 2017, it seems fixed, but I guess there's a similar bug around.

 

hey thanks, i was waiting for an answer like this, thank you very much, by the way, can you check my Animator file for me?

 

Nope!
