WireGuard help

I set up WireGuard and it working OK on Cell and another peer-to-laptop they lose all connectivity to the internet on wired/wifi PC on LAN ( Cell is still Connection OK, PC no Connection)

Would like:
Cell
PC
at some point Site to Site.
All with Split tunnel / Internet goes out local and access to internal.
I have VLAN10-14 as LAN and VLAN15 as VPN
does not have split tunnel work as this time.
Trying to do this in Luci if possible

What config files will help?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, Wireguard keys, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/firewall

At the same time, the configuration files from cell phone and PC would be of interest.
