Constant crashing. This is unreal.

Zero mods.  Bought spaced out and installed, started a new game.  About 70 days in I started getting crashes again and now I can barely go 2 cycles without a crash/black hole ate your game.  I give up.  If I was under the 2 hours played, I'd refund.  Not knowing WTF is causing this issue is infuriating and I'm just tired of it.

From your logs it looks like the game is sometimes having trouble writing the save file. OneDrive or Controlled Folder Access could be interfering with the game. Try excluding the OneDrive/Klei/OxygenNotIncluded folder from OneDrive or temporarily disable OneDrive to see if it fixes the issue. Also check Controlled Folder Access to see if the game is mentioned as being blocked, though I suspect your issue is with OneDrive.

Weird, no idea why OneDrive would be syncing that folder.  I'll give it a whirl and report back.  Thank you!

Ok played for about 5 hours and not a single crash after disabling OneDrive.  Looks like that was the issue.  One thing I feel I should mention is that after disabling OneDrive for my Documents folder:  I had to manually copy the documents folder from OneDrive to my PC under c:\users\<username>\Documents.  Might not be 100% required but I had a lot of other saved games in that folder.

It's your CPU I had the same issue. Intel borked something. Reducing the multiplier in the BIOS or with Intel's XTU tool stabilized my system.

You can find a lot about it on reddit.
