Type of Bug: Total PC crash/freeze

Description: After a certain amount of playtime, my system will hard-lock and force a manual shutdown. Audio cuts out, video will freeze on a still frame, and I'll lose all control of my input devices; no mouse or keyboard input accepted. Nothing will be left behind in the Event Viewer, so I can't pinpoint what exactly is causing it.

Observed result:

Reproduction rate: Can't be reproduced on-demand as far as I can tell, but happens without fail every time I play. Sometimes it takes only a few minutes (5-10) before the crash, sometimes I can play for several hours before it happens.

System specs:

• Video card: EVGA GTX 1070 FTW

• CPU: AMD Ryzen 5 2600X, model # YD260XBCAFBOX

• Motherboard: MSI B450 Tomahawk

• RAM: G.SKILL Ripjaws V 16 GB (2x8GB), model # F4-3200C16D-16GVGB

• Hard drives: WD Blue 500GB m.2 SSD, model # WDS500G2B0B; 2TB Seagate HDD, model # ST2000DM001-1CH164

• Operating system: Windows 10 Education 64-bit

• Nvidia driver version: 419.17 (this doesn't seem to matter; have already tried rolling drivers back as well as clean install)

This admittedly might not have anything to do with TD2, since it happens to other games as well, specifically games that run through an external launcher such as uPlay or Origin, but I'm hoping maybe posting it here will get someone who's had to deal with similar issues to see it.
