I have this issue too - while not a fix, I’m working around this issue by adding this autohotkey (v2) script to my startup folder (update program location if needed, and might have to resize window if the servers list doesn’t show up without scrolling)

#Requires AutoHotkey v2.0
#SingleInstance Force

SetTitleMatchMode 2
SEC_TO_MS := 1000

Loop {
	; Wait for AudioRelay to crash (crash window title is "AudioRelay.exe" instead of "AudioRelay" which makes it easier to detect)
    WinWait "AudioRelay.exe"
    WinClose "AudioRelay.exe"
    Sleep 1*SEC_TO_MS
    Run 'C:\Program Files (x86)\AudioRelay\AudioRelay.exe'

    WinWait "AudioRelay"
    WinActivate
    Sleep 2*SEC_TO_MS

    CoordMode "Mouse", "Window"
    ; Click the left-side "Player"
    Click 50, 125
	; Wait 5s for servers to load, then click the first one in the list
    Sleep 5*SEC_TO_MS
    Click 375, 800
}

This shouldn’t occur in the next version. An early access version is available from Announcements
