I have a function designed to update various types of data, and I’m encountering an issue where the try-catch block doesn’t seem to catch a nullptr error when I’m attempting to update buffer data for DirectX.

Here’s the function:

void Stelo_Project::UpdateBuffer_game(unint TypeCom, unint TypeEX, GameObject* ob){
    const char* dataToCopy;
    TransformBuffer tfb;

    try{
        switch (TypeCom) {
        case ComponentType::Transform:{}
        case ComponentType::Material: {}
        case ComponentType::Light: {}
        case ComponentType::Mesh: {
            mesh_game = ob->GetComponent<Mesh>();
            device_game.d3d_DeviceContext->Map(buffer_game[TypeBuffer::mesh].second->d3d_Buffer, NULL,
                D3D11_MAP_WRITE_DISCARD, NULL, &map_game);
            memcpy(map_game.pData, mesh_game->Vertices.data(), sizeof(Vertex) * mesh_game->Vertices.size());
            device_game.d3d_DeviceContext->Unmap(buffer_game[TypeBuffer::mesh].second->d3d_Buffer, NULL);
            device_game.d3d_DeviceContext->IASetVertexBuffers(0, 1, &buffer_game[TypeBuffer::mesh].second->d3d_Buffer,
                &PosStride, 0);
            device_game.d3d_DeviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST);
            break;
        }
        }
    }
    catch (const std::exception& e) {
        std::wstring wstr = stringToWstring(e.what());
        Debug::Log(wstr);
    }
}

and this is what happened

Can anyone tell me what’s going on.
