System Workbench for STM32

CAN1_RX0_IRQHandler never fires

I am using STM32CubeMX v5.1.0 to generate code for STM32F746IGTx, and have encountered a bug/problem that I am unable to overcome/fix.
As the title states, the CAN receiveing message interrupt is never fired, whereas the transmit interrupt works as it should.
I have validated that the signal on the MCU pin is valid, and should trigger an interrupt, but it does not.
Any suggestions how to troubleshoot this, or perhaps this can be patched(asap, please)?

Thanks in advance,


CubeMX does not generate MX_CAN1_ConfigFilter(); to the main function.
