STm32H723 2nd CAN channel not triggering interrupt!

My first CAN channel functions like there is no issues, my 2nd CAN channel will never trigger the Rx INT callback. I have it pointed at RxFifo1 but it also did not work pointing at RxFifo0. When I disabled CAN1, and CAN2 became the only Rx, it worked as well. I suspect there is an issue with the 2nd CAN channel and buffers. This code worked on a STM32G4 with no issues, so I honestly dont know what I can possibly be doing wrong here!
