Nothing in your crash report ever indicates the problem has anything to do with any of our software, which seems to be confirmed by your report that it happens ONLY with the PMDG 777 and 737.
KFLL is a very simple scenery, so it's far less depending on our software than our later sceneries so, it must be something else.
A common case of users convinced the airport must have a problem "because it only happens there", might be caused by an AI traffic plane, one that due to schedule and time appears only on the affected airport so, you might easily mislead thinking the airport itself might have a problem (because it won't happen elsehwere), but it doesn't.
