The easiest way to fix this issue is to update Unity to the latest revision for your current version. However, if that’s not an option, here is a workaround to get your animations to work again after death.

AAnimationStrategy.cs Replace this method:

public void Resume() => m_animator.enabled = true;

By:

public void Resume()
{
    m_animator.enabled = true;
    m_animator.Rebind();
    m_animator.Update(0);
}
