Metahuman hair bug | After updating to 5.4.1

Hi! After upgrading to version 5.4.1 on Mac OS, metahuman’s hair began to fail. In windows 10, but in they are fine.

The hair crashes if you connect an animated bluprint made in an older version with metahuman animation to it.

Is it possible to fix it somehow?

With connect older Anim blueprint.
