Empty F-PLAN page in MCDU

[NachoTemino]

Hi, Have an issue with a empty flightplan screen in the MCDU, as in this picture:

I have installed, deinstalled A320nx and tried every version (stable, dev, experimental..). I have unistalled a reinstalled MSFS. I have even Reinstalled Windows 11.

After a fresh Windows 11 install, a fresh MSFS install with no other addon but the A320nx I Use the "usual" procedure:

• Dispatch a FP in Simbrief
• Start the flight only with the departure airport, at a gate not a the runway.
• Set Simbrief user in the flypad
• Load the flight from simbrief in the flightpad. Set Weights and fuel.
• From Cold and dark airplane I set power to the systems both external power and batteries.
• Align IRS system
• MCDU ATSU -> AOC -> INIT Data request
• MCDU ATSU -> AOC -> W/B -> Request Send -> Boarding Start
• From the INIT-A page -> Init request
• Everything looks ok, departure and arrival airports apperas in the INIT page
  But then I press F-PLN key in the MCDU keyboard and that same blank page with the strange squares at the top appears

What the hell am I doing wrong? FWB A320nx is the only reason I use MSFS.
I am thinking of going back to P3D if I cannot find a soultion for this.

FBW only supports the latest version of MSFS...
