I managed to get into a plane after waiting the sim to settle at airport (all assets loaded). Entering VR was successful, but then right speaker sound got distorted. Tried exiting VR then reentering, that crashed it again.
I tried to fix local files via Steam, but it affected only the Steam package, and (I guess because of this) it started to download the 107Gb update again.
After browsing the forum nobody else have similar issues, so I think I’ll try a full reinstall, but first I will definitely save all my keybinds and settings.
Anyway, thank for taking the effort to help!
