The traction control will come on once in a while car shakes when driving at higher speeds. Invalid data?

Yes, this happens when one of the wheel speed sensors is going out, the ABS system should have stored the code though. Please go over this guide to get the code and fix the problem:

Was this truck in a flood or an accident? It looks like the BCM has gone out, but I would start by checking all fuses with the systems on. This guide can help:

https://www.2carpros.com/articles/how-to-check-a-car-fuse

The U0422 code in a 2017 GMC Sierra indicates a problem with the "Invalid Data Received from Body Control Module" or BCP (Body Control Module "B").

The U0401 code is a generic diagnostic trouble code (DTC) that indicates a communication problem between the Engine Control Module (ECM) and the Transmission Control Module (TCM)

Here are the fuse locations so you check run the test and I have included how to change the BCM out as well, you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know how it goes.

It has never been in an accident or water damage. the multimedia in the car does act up especially when I’m on the phone using Bluetooth the car seems to always disconnect and reconnect and other little issues of the sort.

Also, is there a reason that all those codes are coming from the EBCM?
