Hi @iniBuilds,
I noticed, that when setting up the plane from cold&dark, and the IRS is already aligned, then during QNH afjustments the sim is freezing.
It doesn't happen to me being on the ground before IRS is aligned or when setting up plane before decent being airborne (when it's set to STD).
I've checked that on 1.1.9 version (MSFS 2024 / XBOX Series X)
