Game crashed while saving. This is the 3rd or 4th time this game has crashed in 400 hours of play, I don't have logs from previous crashes. I will post future ones.

Attached, log, dump, mod_list and the latest save.

Likely unstable hardware, see 114778. If you find a way to reproduce this let us know.

Since crash happened during I/O write, I suggest to check Windows Journal, System tab, for I/O errors. Filter for errors, and scroll until you find exact timeframe when crash happened.
Also, analyse SMART attributes for your drive, and do SMART Long Test.

Only errors at that time were related to Windows Gamebar. SMART says drive is okay. I don't think I can rule out hardware. I think the I/O MIGHT be a red herring because we have had multiple crashes over the 100s of hours and it never crashed on a save before. I reported this because it happened on a save but there might be some catastrophe bias (I lost 15 minutes of gameplay instead of the average 7.5).

Here's the windows GameBar log:

Looks to me like the state of the electric network got corrupted in memory and when trying to serialize it it crashed. So I'd expect it to be a memory or cpu issue. The gamebar thing I don't see as related.

Next step will be stress testing CPU and RAM.

Please run Memtest86+ and Prime95. You can find them here:

https://memtest.org/
https://www.mersenne.org/download/

Run each test until PASS, or overnight.

Ran both tests for RAM and CPU. No errors for either.

Could be one-off then, a random bit-flip, so rare that you can't see that in daily use. Non-ECC memory may be culprit here. You cannot prevent or ever fix that, unless you move to ECC memory in the future.
