I have a fresh project in Unreal Engine 5.5, it has 3 Metahumans in it and I’ve been animating them with LiveLinkFace and sequences. But I have run into consistent crashed when using Unreal. It will crash every single time. The error I get on the crash is; Error: appError called: Assertion failed…

Repeating crash when working with Metahumans

Seems to have been fixed in 5.5.3 → should be released soon.
