Hi, I have the exact same issue - using TCA Sidestick, Throttle + Addon. I never had problems - but since I installed Windows 11 - with fresh install of MSFS2020 - i cant play anymore when Sidestick+Throttle is connected. Drivers are up to date - CTD comes while loading - sometimes I make it into the cockpit - then it happens mostly when using the hat switch… If I unplug everything and use the xbox controller, no problems…(I even deleted all the profiles and set everything to standard…)
Only Addon in the community folder is FlybyWire Mod
