my own w5500 ethernet pcb with esp32-wroom-32e

Hi All,
I designed my own w5500 ethernet PCB with esp32-wroom-32e but it is not working and i don't know why. I checked a lot of different designs and all are similar. I don't use AVDD and AGND so i removed ferrit beads and connect to directly 3V3 and GND.
When I power on the pcb, RJ45 connector green LED always on. There is no blinking when i connect cable or unplug cable. I try to connect modem but I don't. There is no connection when i check modem interface.
Esp32 SPI pins are; SCK:IO18, MISO:IO19, MOSI:IO23, CS:5, RST:33. So anyone get this issue?
