N55 135i all warning lights, no tach, nothing

Drove to school, parked the car, then 8 hours later when I go to start it, nothing happens when I press the ignition. I try again, and the car starts, but it now has every single warning light as well as 52 error codes. Voltage is a steady 14.5. The lights also include all the little images in the lower center square like the lift post light, airbag light, as well as others I don’t know how to describe. Turned the car off and on again, but this time there are no lights. No tach, no blinkers, no stereo, just the ambient red light. While driving it’ll go between that and the Christmas dash, no apparent cause for when it switches.
Errors include PT-CAN errors, K-CAN, and terminal 15 line from CAS short to earth.
Any help is appreciated
