If an instance starts seamlessly travelling while talking in the session's voice chat, the ensure in FScene::Release will be hit, often with the instance then crashing soon after (such as in FAudioDevice::StopActiveSound or FAudioDevice::StopSoundsUsingResource). This does not occur when using non-seamless travel, or when no input is being provided to the microphone as travel starts.
Have two instances connect to each other through the session interface (i.e. one instance creates a session while the other finds and joins the session). Once connected, enable voice chat for the instances, such as with the "ToggleSpeaking 1" console command. Then, while one of the instances is actively providing input to their microphone, initiate a seamless server travel.
