I’ve tried it through both USB connection and Bluetooth. No matter where I am in the game, whether it be the main menu, in a game world on in the plaza, connecting my Switch Pro controller will cause the game to lock up on the spot. Even after disconnecting the controller, the game remains frozen forever until I end the process with Task Manager. I was able to play Accelerate with the Switch Pro just fine in 0.10.1.0. If I have to venture and uneducated guess, maybe this issue is caused by the switch from digital to analogue input for joysticks?
