Man! I think you’ve hit the nail on the head!! 
IA Offline Traffic = Off
I’ve spent an hour with the simulator trying to “break it” (entering to flight, changing cameras, exiting to the menu, flying again, etc) and it hasn’t given me any CTD!
And on top of that, the performance of my PC has increased… +15 fps!

Thank you so much!!! 
But I still don’t want proclaim a victory!.. I still don’t fully trust this msfs
