Crash, GPU-CPU hog, can't load delves

I've been an avid player since joining the start of Bestiary (1K hours) and haven't had major issues until today. I play on a Windows Surface Book via Steam. Starting about an hour ago, the game has been unplayable. With just the game open, my GPU/CPU are maxed out. The game consistently disconnects on the delve loading screen (loading the instance after I click the node to explore).
After closing the game, it still shows up as taking up the same amount of memory. The computer hums fairly loudly until right before I turn it off.

The problem appears to start when the game is first loading. If I had to speculate, the delve instance isn't causing the problem but is the feather that breaks the camel's back.

Have tried with vsync on and off and neither seems to make much of a difference.

This is task manager on a fresh reboot after trying the game again. It's been about 10 minutes since I closed the game.

Please ignore. The problem seems to be with my computer, not with the game.
