Welcome back:
It could be several things including an ignition switch, body control module, grounding issues, power issues and so on. New vehicles/manufacturers incorporate so much technology and computer run components. Even the throttle pedal is no longer attached to the engine, but rather the accelerator pedal position sensor (in the vehicle) sends a wireless signal and a computer (Electronic throttle control actuator) which determines how far you are pressing the pedal and how much to open the throttle.
With that in mind, a tech needs to scan the computer for diagnostic trouble codes. Once the codes are found, they will point the tech in the direction of the problem. Also, since you lost other electrical components, I feel like it is most likely a computer related issue or the ignition switch itself is not sending power where it needs to be.
Please feel free to ask more questions. It is just hard for me to pinpoint anything without codes. I miss the old days. LOL
Take care of yourself and I would really be interested in knowing what is found as the problem.
