P3Dv5.4 freezes on EVERY flight shortly after liftoff

Hey guys 🙂

I’m flying the professional Airbus in P3Dv5.4 all updated. Windows, drivers etc. all updated. 
Other components in the sim with scenery, Active sky and such is also up to date. Tho some sceneries are v4 products.

So my problem started a week ago very suddenly. I made no changes in my sim nor my computer from the many successful flights to the start of this issue. Shortly after takeoff (somewhere between 10 second and 15 minutes) the sim just freezes. With my 5+ year on P3D it feels like it’s trying to load something heavy. 
After 10-20 seconds it unfreezes and continue smoothly for 30-60 seconds and freezes again. Some freezes triggers the “Not responding” in the window and few triggers CTD.

I started doing tests! Deleted scenery, flew without active sky, other places on the planet etc.

No matter what, the problem was the exact same. 
Then I tried other aircraft’s for the same flights, like airports/altitudes… and nothing happened. The sim ran smoothly as ever. PMDG, QW, Carenado, Alabeo and default aircraft and many more. 

I conclude that only the Aerosoft Airbus has this problem for me. GSX, UGCX and everything works perfectly on ground and so does the aircraft, not even a lag. But in the air this issue occurs every single time. 

I uninstalled every bit connected to Aerosoft Airbus and restarted my PC. Did I full install and setup from scratch. The exact same behavior continues.

I hope someone has ideas, missed updates or just something in mind.
