Everything breaks after updating SDK v64 to v67

I have been having problems implementing passthrough, so I thought that updating the sdk version would help. The core and interaction sdk's update just fine, but the all-in-one completely breaks the player controller and hands. The scripts turn into (Script) and when I try to reattach them it gives me an error popup so I can't fix it myself. It seems other people have had this same problem but I haven't found any solutions yet.
