BeamMP Launcher closing itself while I connect

I just downloaded both Beam.NG Drive and BeamMP and I was trying to join a server with a friend. Since it was my first time logging into that server it obviously had to take some time to download all of the mods. But for some reason, the BeamMP Launcher keeps closing itself while the mods download so I’ve had to reopen BeamMP several times over to try and download the mods required to get into the server. Any help would be nice.
