Ran into this few times. Was playing Hunt. Entered lobby, everyone selected characters and once screen went black with “Loading” at the right bottom I got “Connection to the host was lost” (can’t remember exact wording, message was longer than that).
After that game had no sounds at all until I passed another lobby’s loading screen.
Not sure if this was at my end, so has anyone else ran into this?
/Edit: This also happens if you back out during last few seconds after game is proceeding from character selection screen, after the 5 second countdown.
