Hey, I have the same problem so I won't open a new thread but try to provide more info to fix it.
For me I have planes that always work, no matter what, and then some planes that almost never work and have the problem.
Planes that always work: Just Flight Duchess 76, Torquesim BN-2, JF Archer, Thandra PC6.
Planes with the issue: Airfoilslabs King Air 350, sometimes the Bonanza.
I will add logs so you can compare:
