Version 2.50 CTD 2 hours into new game

[MarvinTheMartian]

Not sure what help this will be, CTD without message (so no crashdump I can find) about 2 hours into a new game start (Young Gun)

Found an anomaly and ended up in Silent Witness XI, did a bit of combat, scanning and exploring, and happened across a databank or whatever they're called. After repairing 4 pressure leaks was looking for the next, moving around in the spacesuit holding W+D with the occasional boost with TAB while yawing left with mouse holding button 1 and next thing I know I'm staring at my desktop. Did do a couple of pauses and alt-tab during the game.

Game updated recently 2.50 (347489). Changed steam library before starting the game - promoted to NVMe SSD from a spindled RAID1, Steam did a little 0KB update after this. Also updated Nvidia drivers today, 431.60 clean install. Not much else running at the time except Chrome and task manager.

I'll find somewhere to host the Vulkan Info and DxDiag output but for now:
