PC Issues, multiple games

I'd played through Yakuza 0 on PC with little issue, the occasional crash here and there, but nothing major. But once i hit the finale, my game began going black and crashing during gameplay, i can sit on the main menu for as long as i want, but seconds after i load my save my game crashes.

I've since started Kiwami and have the same issue, i can watch cutscenes all I want, but once Kiryu hits the streets i have precious minutes before my game offs itself. I've searched high and low and i cannot find any mention of anyone else having this issue anywhere else?
