Using cloth and skinned mesh renderer in 2018.4 messes up the renderer bounds. The renderer bounds end up being outside camera view and the object is culled and not rendered. Here is a quick fix how to force the renderer bounds to correct position. https://issuetracker.unity3d.com/issues/adding-cloth-component-to-skinnedmeshrenderer-changes-bounds

FixSkinnedMeshRendererBounds.cs

using UnityEngine;

namespace _Framework.Scripts.Util
{
    public class FixSkinnedMeshRendererBounds : MonoBehaviour
    {
        [SerializeField] private SkinnedMeshRenderer skinnedMeshRenderer;
        
        private void OnRenderObject()
        {
            skinnedMeshRenderer.localBounds = skinnedMeshRenderer.sharedMesh.bounds;
        }
    }
}
