It could be linked to the issue experienced in this thread - which, to me, sounded like a hardware issue, like you suspected initially. But none of the three users who posted this (including you) appear to have any hardware configuration in common. Also, it appears that the crashing is in a different part of the gameplay…
Have you monitored your memory usage in task manager during gameplay? I think a memory leak would show up there.
Also, you mentioned checking logs - were those only the windows logs (Event viewer, reliability monitor, memory dump) or also the unity crash log for phoenix point?
If you didn’t check the unity crash log, I think it’s in:
C:\Users*Username*\AppData\LocalLow\Snapshot Games Inc\Phoenix Point
Or possibly **\local\Unity\
Maybe there’ll be something there that could help you pinpoint what’s going on…
