CAN bus problems

I have an Odrive V3.6 connected to a microcontroller via CAN bus and I also connected an absolute can encoder via the same CAN bus to the microcontroller (the encoder is not for motors) .
The microcontroller communicates with the encoder but when I power ON the Odrive, the communication stop working.
The encoder and the Odrive have different power sources and are connected to microcontroller via an isolated transeiver .
Can someone help me to understand how Odrive V3.6 influences the communication via CAN bus?

Thanks !

Hi! You asked this on the Discord as well, correct?

Yes we discussed on Discord , thanks !
