Global AP issue since reinstall

Hi there,
After a disk failure i had to reinstall msfs and since then, I noticed something weird with all Autopilots (Garmin/classic).
Vertical navigation is working as intended but horizontal navigation (both heading and nav) are not working as it should despite their indicator activated correctly.

AP is on, HDG is on and the plane doesn’t react at all to the AP. The plane goes immediately into a spin.

I removed all my plugins / mods without success.

Any ideas before i redo an install ?

thanks
