Nobody ever reported this in about 10 years KDFW is out.
A common problem that often mislead users that a specific airports has a problem, because the sim crashes when approaching there, it's a problem with missing/corrupted files for an AI and, if because of its schedule, the problematic AI appears mostly on that airport only, it's easily to be confused and blame the airport, because it seems to crash only there.
The first thing to try, is to test with 0% AI Traffic, and see if the crash goes away. If it does, you can be sure it's not the airport.
