[2019] Rocket League mouse problems

Hey all,

I play on MacOS with a mouse and keyboard, and this is the first time this has happened to me: whenever I launch the game, the camera/mouse goes crazy. I can't click on any buttons, I can't even switch between cars or properly switch between playlists because everytime I move my mouse to do so, it moves the camera for the car in the menu screen.

If I try to click "Casual" in the queue while I'm at a different tab, instead the 3v3 or 2v2 playlists will be selected even though my mouse is at the "Casual" tab.

Any ideas on what's happening and how to fix it?

Edit: specified the OS
