Try Loading a Manual Save
Some players have said in Reddit posts that they’ve fixed the LowLevelFatalError Stalker 2 crashing by loading manual game saves rather than automatic ones. Admittedly, this might be more of a workaround than a fix that could be worth trying. If you have any previous manual saves, try loading the most recent one to see if the crashing persists.
