UE4 Crashing when I try to import Apex Hair

Hello, I’m working on APEX for my main character. The dress is already working perfectly with kinematic ragdolls and stuff, but the big problem is when I try to import and activate my Hair Apex Mesh.

The error is:

MachineId:59D6EB224BB479A193D0F0B449878BAD EpicAccountId:8477484b58a9404ab52af94ee3c5e4e4

I’m not sure if it’s just a session ID but I would remove the EpicAccountId from this dump…
