Describe the bug

When you stop the game in the editor (while another window you open via Join via new instance is running) the other game window freezes. However, it accepts inputs. I can still press the tilde key and open the console and type and input commands. But sometimes, it refuses to accept input.

To Reproduce

Start a session. Join via new instance. Stop the session in-editor. The new instance window is frozen but still accepts input.

Expected behavior

Just take us back to the main menu if the session is terminated.
