W5500 and UWB not Working Together with ESP32

Question

Hi everyone How are you.I am working on a Project right now in which I am using Esp32 with UWB to get distance. Now We can also send reading received by MQTT but I need to get the readings by Ethernet via W5500 Module. No when write code only for uwb i can get the distance readings from another similar PCB.But when I add code for W5500 both devices are initialized but UWB is not getting reading from Tag and When i add delay to initializw W5500 the I can recieve distance readings but W5500 failed to initliazed.Please Note W5500 and UWB are on Seprate SPI busses W5500 is on HSPI with different Cs and UWB is on VSPI.Can any body has any idea why this is happening.As i am using seprate SPI busses why its not working properly I can share more If any one has idea about this Thanks
