In the past 24 hours, I have come upon a problem with ALL aircraft shutting down engine(s), it;s happening with Jets, Turbo Props, Twins and Single Engines.  I have not made any MOD changes in the past few weeks, the only change has been

iinstalling a new 32" BenQ Monitor and made change in Graphics settings to accept the new monitor.

 

Any help appreciated

There indeed has been some strange changes recently. 

Since the updates in content manager saying new ver. needed for update, MSFS has been unusable for me.

Every flight starts with the airplane engine running, and none of my controllers working. 

If I use the mouse to pull back mixture control to shut engine down, the mixture lever creeps back to the full forward position. The same is true for the prop control. The throttle control is the same except  it remains in the idle position. 

My Honeycomb yoke has no effect on the roll or pitch axes, nor does my Saitek rudder pedals affect yaw or brakes. Its as though no controllers are installed, but if I go to controller settings I can see they are installed and I get the animations when I look at the sensitivity settings.

I have tried to do a reset of MSFS which took 12 hours. Results are the same.

I am at a loss regarding what next to try.  

Sounds like your computer is running on the old engine engine.  Maybe update the engine engine so that your engines run on the most recent engine engine.
