EXC_BAD_ACCESS on bool BaseConnection::Open()

[Lyceion]

Hello everyone. I have a problem. I'm trying to test integration of discord-rpc on my program. Currently devolping on "MacOSX, BigSur 11.2.3". Added:

• connection_unix.cpp
• connection.h
• msg_queue.h
• backoff.h
• discord_register_osx.m
• discord_rpc.cpp
• rpc_connection.cpp
• rpc_connection.h
• serialization.cpp
• serialization.h with rapidjson from tencent.

Also included all includings. And it is compiling with ne errors. But when i run program, it has bad access on BaseConnection::Open(). And it returns self, this NULL as you can see on screenshot bellow.

Also initializing RPC with:

void DiscordRPC::StartDiscordRPC(){
    DiscordEventHandlers event_handler;
    memset(&event_handler, 0, sizeof(event_handler));
    Discord_Initialize("clientID", &event_handler, 1, "123");
    UpdateDiscordRPC();
}

void DiscordRPC::UpdateDiscordRPC()
{
    DiscordRichPresence discordPresence;
    memset(&discordPresence, 0, sizeof(discordPresence));
    discordPresence.state = "test";
    discordPresence.details = "test";
    discordPresence.largeImageKey = "picmin";
    discordPresence.largeImageText = "test";
    discordPresence.partyId = "ae488379-351d-4a4f-ad32-2b9b01c91657";
    discordPresence.joinSecret = "MTI4NzM0OjFpMmhuZToxMjMxMjM= ";
    Discord_UpdatePresence(&discordPresence);
}

Calling StartDiscordRPC() in program start for once and calling UpdateDiscordRPC() on my program's update event. Program crashes from start. Even before calling UpdateDiscordRPC().
