Unreal Engine 5.4.3 Crashing when try to open Metahuman BP.

Hello @unit23 , not i’m using a 5.4 Metahuman Version created from Metahuman Creator, but this happend until with the demonstration metahuman of Motion Matching Game Animation Sample Project.

After some lot of additional test i discover that my metahuman is loading but the problem is around the Groom of the Metahuman.

Is the Groom that crashes my engine, but i don’t know why
