I think this can be fixed by first understanding that a VPN is a proper network.

You do not have to rely on the qbittorrent client to do any proxying. Turn that setting off.

A wireguard VPN is literally a network that you can route traffic through. If you can somehow force qbittorrent to route all its traffic through a wireguard interface and not your wifi/eth interface, you wont need the proxy settings as your IP will be hidden by virtue of you using the wireguard network rather than your home network.
