Your right, it is causing a crash (CTD) on all planes.
Since my screenshot indicates it's not crashing with the PMDG 747, it surely cannot crash with all planes.
Once I uninstall KLAS then the problem goes away. I searched the FOrum. I found no known ctd issues posted that I can troubleshoot by
Of course, since the problem is not the scenery, nobody ever reported it before.
.Can you help me please?? Your KLAX works fine, so does GSX
It's very common that users are lead to believe that a crash that happens on an airport and disappear with the airport uninstalled, might be a problem of the airport scenery. However, most of the times this is not the case.
A common cause might be a problem with an AI, like missing or corrupted textures or other files belonging to it. Due to the change in the number, size and airline codes of the parkings in the add-on airport compared to default scenery, it's possible the offending AI might not appear if you revert to the default scenery, which can easily misled you the scenery must have a problem, but it doesn't.
This is usually troubleshooted by setting the AI Traffic density slider to 0%. If the crash stops, then you are sure it was caused by an AI.
