I can use the Main Menu, I can change Options with keyboard and mouse, but I cannot use "Join" on starting a game with Keyboard and Mouse. I get the game suggests I use a Controller, but why does it stop letting me use a keyboard after the main menu

Languege instead of "Language" UIvloume instead of "UI Volume"

The game crashed to desktop after I finished a round in the training area and tried to go to the door on the right after selecting a class. I'm not really sure if this is meant to be a Survivors game or something else, but it doesn't feel great solo playing and taking ages to kill anything, also can't escape the wizard's black hole effect with dash. This is rough. It's interesting, but I would need a better look at the actual gameplay to buy this....
