I know this is not directly the same thing but maybe it provides a clue. I just attempted to move the AIG beta folder out of my community folder. Left the CSL from IVAO and attempted using PSXT traffic with AIG; which is what triggered a CTD and it has not crashed at all with those models vs the AIG. Perhaps because there is less models to choose from, so it does not cause a crash?
Just thought I’d give some insight into what happened to me tonight regarding this.
