ADC out of range, mcu shutdown, abnormal bed heating

Apologies if this has been already asked, but I tried looking up this issue and I can’t make heads or tails about possible as solutions (or if I’m even having the same issue).

I have a Ender 3S1 Pro(2024 edition) and installed a Creality Pad. Everything worked fine for the first ~two months, but last week I changed from a wired Ethernet connection to a WiFi connection and attempted some prints. The first print was fine, but shortly afterwards I started seeing errors regarding abnormal heating. The screenshots I’ve attached are from the Creality Pad and the Printer IP when I connect directly.

Something else I should mention is that the hardware and software are telling me that my heater bed temp is ~220C at startup (and so is my target temperature, which is bizarre). When I touch the heater bed its at room temperature…

I suspect this is a heater bed issue / sensor issue, but I’m not sure how to begin troubleshooting. I opened the underside of the printer and all of connections and cables look to be okay.
