No matter what I do, my plane doesn't move during taxi! (noob here)

It can happen if the pushback cart is still attached to the airplane.

Other times the sim may spawn you in a bad parking spot where you are hopelessly stuck.

Just take a peek on the external camera to see if either is the case.

Yea I’ve looked nothing is connected to the plane. Happens in almost every airport I can think of and nothing budges. I’ve done everything possible to fix the problem and it’s not fixed. At this point I can’t even fly on msfs. The problem still persist I’ve reinstalled msfs, reinstalled the planes, reinstalled GSX, Updates GSX, cleared all inputs of brakes, everything I’ve done possible to maybe fix the solution doesn’t work,
