What worked for me is to delele image files which were added in 'SceneKitAssetCatalog.scnassets' folder. I think only 3D objects formats like usdz, scn, obj etc are allowed in 'SceneKitAssetCatalog.scnassets' folder.
And moved the images which were required to be applied as texture to 3D scn object in a separate folder.
