Same for me as well.
Tried several different aircraft but the same bug hits most of them which are the default aircraft. Robin, Cessna and the like. Seems to happen in 2d as well as VR.
Airbus throttle and stick, Logitech mouse, generic keyboard.
i7 9700, Win 10
nVidia RTX 2070Super
32GB, 1TB nvme.
Win 10 and all drivers up to date
Nothing has changed since the last update and it seems to be happening after the AUS WU.
Assigned one of the buttons on throttle to Avionics and it seems to be working on one of the planes but today it happened again on Cessna 172 G1000
