Unity 2018.2.20f1 crashes rig humanoid

How to reproduce:

1. Go to the Project window -> Models -> select model.fbx
2. Go to the Inspector window -> Rig -> Set Animation Type to any other type from Humanoid and press apply
3. Set the Animation Type back to Humanoid and press apply (crash occurs)



Solving the problem at the moment. Make Rig in 2017.3.1 p1 and copy it to the project folder in 2018.2.20f1.

Update "Unity" to version 2018.3 is not possible, due to the lack of a java script.
