PITB board not recognized by CAN network, tool head board in passthrough works fine.

I am trying and failing to have the Party in the back (PITB) board recognized.

I know the CAN wiring is correct, because I have it daisy chained with a toolhead board (downstream of the PITB) that is running fine on klipper, it's just the PITB board that isn't running

I'm using these settings https://github.com/kageurufu/PITB/tree/main/firmware
I am able to see the board over USB, but once I put it into the CAN network I see just the toolhead board like below.

I have also double triple checked the wiring on the board and made sure it is getting the appropriate power.

I am following esotericals guide online, including all of the steps for troubleshooting no UUID, I have reinstalled the katapult software multiple times, each time it appears to install normally.

FWIW, I did have to take down the CAN network and then bring it back up with 1m and qlen 1024, and that worked for the toolhead board (ebb36) that I was able to successfully install klipper on.

I have also removed the ebb36 from the loop, and am now just trying to flash the PITB on it's own. I have also tried with and without the CAN FD Jumper

Also to note, I am using the btt u2c board. Once again I know that board is working, as the tool head board was successfully flashed with katapult and then klipper.

Currently the pitb board has been flashed with katapult, but I cannot see over can
