Toolboard shutdown: "ADC out of range" after changing nozzle
I removed my nozzle today to switch from .6 to .4 and as soon as the nozzle came loose, klipper immediately shut down due to not heating as intended. Upon installation of the new nozzle and a firmware restart, klipper throws this error. I've been printing fine with this exact setup for months with no issue. My last print was Thursday of last week and it was flawless.
I have an EBB42 v1.2, Rapido UHF, PT1000, crimped connections, and have double checked that everything is tight. The jumper for the PT100 on the toolboard is working as it displays two very different numbers when removed. The only thing I've done today other than change the nozzle was to update everything available from the machine tab, which gave me problems as well like breaking the RatOS Git link or something, but I resolved that through manually updating in the right order. I also tried reflashing the toolboard through the configurator
I tried changing the value of the pullup resistor like I saw in a recent help post to no avail. Don't know what to look for or how I managed to brick the printer by changing a nozzle. Any help would be amazing, happy Monday!

Errors connecting to ratos.local, no hotspot for new RatOS image
A few days ago my browser would no longer connect to ratos.local which I had been using steadily since I built the V-core 9 months ago. The printer has been on my company's wifi, while my computer has been hardwired, and there have been no problems.
When I configured everything to begin with, I don't think I changed any of the SSH information, but I was unsuccessful at trying to get into the Pi. I must say that working with an OS other than windows is foreign to me, networking is not my strong suit, and I've never owned a Pi until I built this printer. I also don't have access to my company's router/network, so I don't even know the IP of my Pi. I'm currently waiting for a reply from our IT guy so I can get into the network.
My next problem started when I thought the easiest/fastest solution was to clear my Pi's SD card, and flash a fresh image of RatOS to enable the Pi's hotspot and go through the configuration again. Upon doing so, the hotspot never appears. I've tried looking for it with multiple devices, nothing. Waited over an hour. Tried restarting the Pi with the same results, no hotspot. at this point I have tried 3 different SD cards, the most up to date version of Balena Etcher, and the latest as well as the previous versions of RatOS. I even tried entering the wifi information manually in wpa_supplicant to connect to the same network it was previously on, as well as running a LAN straight to the Pi with no results.
I've never had to attach a screen or peripherals to the Pi, but trying this also did nothing.
I'm at my wits end, it was my understanding that a new flash of RatOS would clear everything and allow me to start over. What have I done wrong? Is my Pi fried? Did a networking error become something greater? Any help would be appreciated beyond belief.
