[CLIENT] [CRASH] Client not recognizing absence of match, leading to unresponsiveness and crashing

After I left a custom game (only one player, no bots. I was trying to recreate a bug), the client did not recognize the match no longer existed and I was given the "You have left a match in progress" screen. I then pressed reconnect as that has previously caused the client to recognize that there is no game to connect to. Instead, the program put up an all-black screen and was unresponsive; alt-tab would not minimize the black screen and only brought up the task bar. After waiting, this error message was displayed shortly after (I do not actually have a problem with my network/internet connection): https://imgur.com/AYUFDIB Having to end this via the Task Manager worked but resulted in the client being showing no items and being all black as well with only the bottom bar with the Friends List, Chat Room, and Notification button being visible. I then closed and restarted the client which then crashed and BugSplatted on restart at the "Launch" screen.

In summary the issues were:

1. Client did not recognize the game ended after exiting.
2. Pressing the reconnect button resulted in an unresponsive black screen.
3. Ending the black screen resulted in the client not displaying its features.
4. When restarting client, client had a crash and bugsplat on "Launch" screen.
