Repeated crashes to desktop with no error message, independent of CC status

Howdy all. I've been trying to figure this out on my own and am completely stumped - any insight from someone who understands TS4 better than I do would be very appreciated!

Basic situation: Game will be playable for anywhere from 30mins to ~2hrs, then slows down for about 2 seconds and closes to desktop. This happens even without CC, and I've done a reinstall. I've crosschecked my specs with the minimum requirements and everything checks out. For reference, here they are:

Operating System: Windows 10 Home 64-bit (10.0, Build 17134) (17134.rs4_release.180410-1804)
System Manufacturer: Acer
System Model: Aspire F5-573G
BIOS: V1.18 (type: UEFI)
Processor: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (4 CPUs), ~2.7GHz
Memory: 12288MB RAM
Available OS Memory: 12156MB RAM

Graphics card: NVIDIA GeForce GTX 950M, 4GB VRAM

I have the basegame and pets, both of which are through Origin, not a hard disc.

This crashing issue happens every time I play the game if I leave it open long enough. Attached is the latest crashfile, as well as my computer's DxDiag. 

Thanks in advance!
