When using proxy chain (not supported under current structure), conn is cnc.connection, not *internet.PacketConnWrapper.

In AndroidLibV2rayLite, where effectiveSystemDialer is altered by internet.UseAlternativeSystemDialer, conn is *net.UDPConn.

So type assertion in

Xray-core/transport/internet/splithttp/dialer.go

Line 108 in b277bac

    
           return quic.DialEarly(ctx, conn.(*internet.PacketConnWrapper).Conn.(*net.UDPConn), udpAddr, tlsCfg, cfg)

will just fail and you need hack like

Xray-core/transport/internet/quic/dialer.go

Lines 151 to 161 in b277bac

    
           var udpConn *net.UDPConn 
        
           switch conn := rawConn.(type) { 
        
           case *net.UDPConn: 
        
           	udpConn = conn 
        
           case *internet.PacketConnWrapper: 
        
           	udpConn = conn.Conn.(*net.UDPConn) 
        
           default: 
        
           	// TODO: Support sockopt for QUIC 
        
           	rawConn.Close() 
        
           	return nil, errors.New("QUIC with sockopt is unsupported").AtWarning() 
        
           }

or maybe wrap net.Conn to fit net.PacketConn.

And, net.ListenUDP need to be replaced by internet.ListenSystemPacket in https://github.com/XTLS/Xray-core/pull/3554/files#diff-c0d111c26ebe8b3a6a004695c434204a67726f8b6af44d01b601c60573e45601R283 so that internet.RegisterListenerController can take effect.

	var udpConn *net.UDPConn
	switch conn := rawConn.(type) {
	case *net.UDPConn:
	udpConn = conn
	case *internet.PacketConnWrapper:
	udpConn = conn.Conn.(*net.UDPConn)
	default:
	// TODO: Support sockopt for QUIC
	rawConn.Close()
	return nil, errors.New("QUIC with sockopt is unsupported").AtWarning()
	}
