Considering the information given and that pretty much all accessories and starter fail to operate.
My guess would be a faulty ignition switch.
But there could be a faulty wiring connection that could cause the same issue.
Suggest you check powers and grounds under the hood and at the ECM are clean and tight.
If that all checks out, using a DVOM test out the ignition switch and wiring.
