    Bug reproduced in Unity 2018.3.4f1 with Android platform selected.
    Problem disappears when GPU skinning is disabled.

    Found the solution for my problem.
    It was because of the GPU Skinning.
    When "On" the editor does not compute the blendshapes and gives this errors.

    Bug reproduced in editor with Android platform selected in Unity 2018.3.3f1 as well.
    Did not test with the download scene, but with another model with blendshapes.
