A320NX always crashes with simbrief flight plans

I’ve followed many different video guides on YouTube explaining how to setup Simbrief flight plans using the MCDU in the A320NX but every time I turn the autopilot on, the plane just banks hard to the right, and then the airplane crashes in the ground. Is it just impossible to setup a flight plan from in game using the MCDU now? Autopilot only works when I generate and load the flight file, but I want to generate flight plans from in-game too. I can’t think of any reason why it isn’t working… I did everything they said to do in the videos like setting route from KORD → KDPA and then DCT DPA with the arrival and everything. I also entered the flight level, calculated v1 and v2 using the calculator, set the payload according to simbrief plan, fuel, watched full startup tutorial, aligned IRS, etc. I takeoff from the runway and when autopilot is switched on, I instantly bank and crash every time!
