Steering locks when I drive

When I want to turn the wheel it locks and I can’t steer so I go that way the wheels were looking. Oh and sometimes when I want to brake it does nothing,it just like selfdriving car that can go just forward.
I’ve texted the support team yesterday,but they haven’t answered yet. Is there any solution to my problem?
Plat: PC - keyboard+mouse

sounds like you are locking up the front tires. how do you vary the rate of braking with a keyboard or mouse??
