ESP32 CANBUS Problem

Hello to everyone,

I am pretty new to ESP32 and I am trying to connect 2 ESP32 with CAN protocol.

I have searched all of the libraries and instructions available on the internet, checked different cards with different modules but still can't form the connection.

I use 2 SN65HVD230 CAN module to connect the ESP32s at both ends. Using GPOI 4 and 5 pins for CTX and CRX connection.
You can see the system here: https://imgur.com/a/UF1UQfv

But nevertheless I can't send message or receive it here you can see the serial monitors: https://imgur.com/a/r8IVQMl
*Here I use the miwagner codes.

Is there anything I do wrong, or a part I miss out?
Thank you in advance.
