As per title, the game suddenly crashes, this does not seem to be related to any particular action since I was always doing different things when the crash happened. In the last week the crashes were fairly random, I can sometime play for 1hr, sometime for no more than 10 minutes before another crash happens.
The CTD's did not happen with previous versions of the game. I updated an old savefile and synced mods.
The game is mostly vanilla with a couple cosmetic mods. I'm attaching both the latest log and the savefile.
Thank you very much for your support.

Post more logs with crashes please.

Another couple back-to-back crashes, with logs and dumps.

Thanks for the report. are you overclocking your CPU or RAM at all? I've never seen a crash in this place in code that was caused by an actual bug in the code. It's possible that you found one, but it's more likely that it's a hardware instability issue related to the threading that belts use (this is something we have seen several times on almost-stable computers)

Not overclocking per se, but I did enable XMP in my BIOS. (AMD FX 8350 Black edition on a Gigabyte 990XA-UD3) Could it cause the quasi-instability you speak of? Is there any workaround?
It's also very random: after those 2 crashes in 10 minutes, I was able to play for an hour uninterrupted, then a crash, then another hour.

XMP has caused these kinds of issues before. Try disabling it and see if it makes any difference to how frequently it crashes for you.
