When using multiplayer play mode in a fresh unity project (2023.1.0b20) on a linux system (Linux Mint 21.1 Cinnamon), virtual players do not activate properly. When activate is clicked, there is no loading wheel, and the word "Activating" appears, but nothing happens. I've left it for 15 minutes and still nothing. No errors appear in the console. If I close the multiplayer play mode window and re-open it, it says the player is active, but clicking play does not launch the virtual player and the mpm window goes back to saying it's inactive.
