When used with Wireguard packet receive causes Guru Meditation Error

[AndyW999]

When using with PlatformIO and receiving a Wireguard packet there is a Guru Meditation Error.

If WiFiUdp is used it works OK but packets cannot be processed fast enough this is why I want to use AsyncUDP .

AsyncUDP works OK without Wireguard.

I suspect that the Wireguard netif is not being found.

Please see attached files.

Thanks

Andy.

I did post to Github
espressif/arduino-esp32#8397
But did not get any response so this works -

IPAddress remote_ip {0, 0, 0, 0}; // IP address of the local WG interface
IPAddress local_ip {0, 0, 0, 0}; // IP address of the remote WG interface
uint8_t rx_buffer[1600]; // received data

void udp_rtp_init(uint16_t port)
{
err_t err;

/* Create a new UDP control block */
upcb_rtp = udp_new();
ip_set_option(upcb_rtp, SOF_BROADCAST);

if(upcb_rtp)
{
udp_rtp_port = port;
if(upcb_rtp)
{
udp_rtp_port = port;

err = udp_bind(upcb_rtp, &wg_local_addr, port);

	if(err == ERR_OK)
	{

		udp_recv(upcb_rtp, udp_rtp_receive_callback, NULL);
	}
	else
	{
		printf("can not bind pcb");
	}
	upcb_rtp->remote_port = udp_rtp_port;

}
else
{
printf("can not create pcb");
}
}
