Asset Importer Invalid Cast Exception

I keep getting an error anytime I run a Unity scene (empty or not) that states the following:

InvalidCastException: Specified cast is not valid.
UnityEditor.AssetImporters.AssetImporterEditor.InitializePostprocessors () (at <44a70d1b13cf47e29810e30f45ffae08>:0)
UnityEditor.AssetImporters.AssetImporterEditor.OnEnable () (at <44a70d1b13cf47e29810e30f45ffae08>:0)
UnityEditor.AssetImporterTabbedEditor.OnEnable () (at <44a70d1b13cf47e29810e30f45ffae08>:0)
UnityEditor.ModelImporterEditor.OnEnable () (at <44a70d1b13cf47e29810e30f45ffae08>:0)

I’m not sure what the asset importer is nor the post processor, how would I resolve this issue?

I get the same problem too!
Do you figure it out?
