This is fairly common; happens to me every time after I've been away from the sim awhile and forgotton. IIRC the trick is to release the brakes AND unlock the tail wheel, ckeck the keycard for the assigned keys. IOW it's pilot error (or amnesia) not equipment failure
But check ingame setup options to make sure the keys are assigned as you're expecting especially the rudder and brakes. IIRC the joystick rudder steering may need set ingame
