Hello
I had the same issue! I installed the Game yesterday and when i started a new flight: always same airport / always same plane.
The issue was my Windows 11 username! It had an “ü” (Switzerland) in my Name so i changed the Windows account name. BUT the name of the user folder was still my old username so i changed the folder Name with this link:
pureinfotech[dot]com / change-user-folder-name-windows-11/ # change_profile_folder_name_windows11
now it works without problems! it was a little bit tricky. perhapts its easier to uninstall the game / create a new user and reinstall again! note: take a simple username
