Unable to click any buttons in Multiplayer

I have a friend, that while he is able to do the campaign just fine, is unable to get any functionality out of any of the buttons once he reaches the lobby.

Trying to join a game fails silently and when we invite him to a game that also fails silently. In his logs he found something related to ntdll.dll

Any ideas?

Edit: He does have MSI Afterburner on but isn’t using the overlay.
