Thermal anomaly on start up with unprompted heating the nozzle and bed

I'm hoping I can repair my broken Einsy.

I've being getting "No LAN Access" message on a specific RPi Zero. The RPi and PrusaConnects worked fine when powered externally. I tried to connect it to the Einsy with jumper wires, skipping the mechanical support on GPIO22. It worked. Somehow GPIO22 was preventing the pi from connecting to wifi. So I decided to snipped it off, and, excited that I finally solved it, I very carefully plugged it exactly where I was trying to avoid, the four pins next to where it should go. I knew I fucked up when I heard something pop (likely the pi) as I turned the power on. Now if I turn the printer on, it screams and shows a temp anomaly error, while heating the bed and hotend for no reason.

Any ideas what could the damage be and if it can be saved?
