Issues with skeletal mesh in Unreal 5.2.1

After upgrading to Unreal 5.2.1 from 5.1.1, my character meshes are rending incorrectly. These characters are using the UE4 mannequin as their skeleton. Seems like a bug, wondering if anyone else has seen this issue? Also not sure, but might be related to this: Tech Note: Issues with Animation Blueprint Library & Animation Modifiers in 5.2
