As it states it seems like a VRCFury component is referencing a gameobject that is attached to the PC version of your avatar rather then the Quest version of your avatar. In the end you need to find where this component is in your quest avatar and check that they reference the quest avatar properly. You could also try using VRCQuestTools to convert the PC version to quest instead and it should fix it. Just depends on what you wanna do.
