Crashes when using Metahumans

[Grinlane_Arts]

Everytime I want to load in a Metahuman into my scene or even open it’s blueprint the engine crashes and gives me this:

Fatal error: LoginId:378ce8154f6037839e64b0ab4fe23699

hi, i have the same problem. if i open metahuman folder, my engine crashes.

I just found out, that it was working until it asked me to enable the hair plugin. I opened a completely blank project and just loaded in a Metahuman. I could drag and drop in the blueprint, was seeing it correctly and when it asked me to enable the hair plugin and I did as it asked it crashed with the same issue…

Same here, Unreal Crashes every time I drag a Metahuman Blueprint into to the scene.

I have the same problem. Please someone help. I cant use DX11 forever.

Well whatever caused the issue, apparently got fixed in 5.4.2, bc I can use MetaHuman again without it crashing

This is due to faulty compilation, and the solution is very straight forward: “Recompilation”.
Go to the following directories and delete everything
1- C:\Users(“yourname”)\AppData\Local\UnrealEngine\Common\DerivedDataCache
2- C:\Users(“yourname”)\AppData\Local\UnrealEngine\Common\Zen\Data\cache
It forces Unreal Engine to recompile every shader.
No reinstallation or update needed.
