Realflight 9.5 crashes when tryi

STIL works okay with any plane model in RF9.5. But for one model (which seems perfectly working in RF9.5), the RF9.5 crashes when I start STIL. What could be the casues ?

I figured out that the SITL causes the simulator to crash when any launching method is applied other than “Hand Launch”. It only works with Hand Launch!

Any idea why? and how to allow for other launching methods (Discus, Bungee, etc) ?

In my case, it only works with “from ground” launch method. The bungee launch make Realflight crash when an SITL is running

Is there any solution to this problem?
