Try to enable the SU10 Navdata API option in the GSX Config panel in the installer, this might fix the problem, if your problem was caused by issues reading the sceneries in the Community folder, usually due to corrupted files, missing folders, or any other issues like antivirus or permission problems, which would prevent the program to create its airport cache.
With the SU10 Navdata API option enabled, airport files won't be read anymore and the airport cache won't be used, so it might fix all the above issues.
