Your log shows a constantly increasing amount of bytes_retransmit and also bytes_invalid

bytes_retransmit would indicate some bandwidth problems on the CAN bus.

  1. At what speed do you run your bus
  2. Have you made sure that all devices and interfaces are using the same speed?

bytes_invalid is considered a serious issue on a CAN bus. See CANBUS Troubleshooting - Klipper documentation
