Need help for OpenWRT with WireGuard

The Official OpenWRT forum link of my post.First of all i know this is not the OpenWRT support forum, I am asking here because they have rejected to help or like ignoring or they do no know how to fix it.
So i was trying to set the wireguard with the openwrt on one SSID wifi and other will work just with normal setup without wireguard. So when i tried it did not give the wireguard SSID internet, as far i know it is a DHCP error or firewall maybe. Also the openwrt based on linux so maybe i can get help from here. Thank you.
