WebSocketMultiplayerPeer server crashes if it's configured with a TLS certificate.

[Vsono]

Godot version

4.0.dev

System information

Windows 10

Issue description

If a WebSocketMultiplayerPeer server is configured with a TLS certificate, the program crashes whenever a client tries to connect.
I don't get any error messages (which is driving me crazy)

I tried with a self-signed (in Godot) certificate and a properly signed Let's Encrypt certificate, but same results.

Steps to reproduce

1. Configure a WebSocketMultiplayerPeer server with a TLS certificate
2. Try to connect to the server

Minimal reproduction project

test_client.zip

Lines 336 to 350 in 19c9fd6

	if (peer.connection == peer.tcp) {
	Ref<StreamPeerTLS> tls = Ref<StreamPeerTLS>(StreamPeerTLS::create());
	Error err = tls->accept_stream(peer.tcp, tls_server_options);
	if (err != OK) {
	to_remove.insert(id);
	continue;
	}
	}
	Ref<StreamPeerTLS> tls = static_cast<Ref<StreamPeerTLS>>(peer.connection);
	tls->poll();
	if (tls->get_status() == StreamPeerTLS::STATUS_CONNECTED) {
	peer.ws = _create_peer();
	peer.ws->accept_stream(peer.connection);
	continue;
	} else if (tls->get_status() == StreamPeerTLS::STATUS_HANDSHAKING) {

Is line 345 causing the problem?
