Thanks for your fast response! Yes, I sent a report of the simulator failure, but I never had one before (I have many aircrafts) and before that I had several crashes with the log message "not enough memory" which is strange for a 32Gb hardware.
Anyway, today I was able to fly with this aircraft for the first time. I just removed the XJet plugin, as you said, and selected "Max FPS" in the LuaGC option in the Gizmo menu. I don´t know if this make sense, but it worked! I only have to try IVAO. Yesterday I had the feeling that when connecting to the network, the failure occurred too.
I want to take this chance to say that I´ve been in the simulation for more than 25 years, I have the best aircraft available, and this is, without any doubt, one of the best. Please don't leave this aircraft
