As the title states, about a minute into rendering the 3d .obj file, the CPU becomes completely unresponsive and can only be "remedied" by restarting. I noticed that my CPU in the task manager was peaking around 99%. However, it may be a different issue as it happens with After Effect v17.5 (used Posterize Time & Time Warp) created the same crash. Two different scenarios the same outcome.
Photoshop Version 22.0
Update Nvidia Drivers
Clear Photoshop Cache

If any more info is needed, send me in the right direction, and I'll get it.
