A crash occurs when you add/drag a skeletal mesh with Apex clothing into the scene. The user reporting the issue managed to find where the crash occurs and added a comment for assistance where to look.
"The crash happens inside ApexClothingUtils::GenerateMeshToMeshSkinningData, in a call to GetPointBaryAndDist with the points passed being all equal. This causes a check to fail in FMath::ComputeBaryCentric2D because the points are colinear."
