BeamMP Disconnects When I Press ESC or Open main menu – Is This Normal?

Hey,
Every time I press ESC in BeamMP or try to open/close the main menu, I get instantly disconnected from the server.
Even when I’m just trying to close a window like the Parts Selector or Vehicle Config, I sometimes hit ESC out of habit and boom — disconnected.
