Summary

When playing the game, I will often get repeated crashes to the desktop, with the message dialogue box informing me that the game crashed and to go to the crashdump location and send it to the developer.

The error log indicates an Access Violation reading from memory. No issues during memory tests, benchmarks, or other games.

I can reproduce some of the circumstances but some of the crashes don't have easily observable (and thus linkable) circumstances. One such circumstance is opening a trade window or a bill window, the crash coming several seconds later.

System and Version
Rimworld: 1.0.2408 (64-bit) Compiled Oct 1 2019 via Steam
OS: Windows 10 Enterprise 1909
CPU & GFX: i5 3570K, GeForce GTX 970

Circumstances
I've experienced reproducible crashes during the following circumstances:

• trading with a visitor - often
• editing bills - rare

When the crash happens while trading with a visitor, it can be several seconds after opening the window, sometimes over a minute later, while I'm mulling over the trade.  For this reason I'm not sure that summoning the trade window is related, but my save currently has a trader in the colony and I can trigger the issue reliably by trading with the visitor and spending some time in the trade window.

I've also experienced crashes that appear to be arbitrary, but it seems more likely that I'm just not aware of the circumstance triggering the crash.

The crashes occur both in my current game and in a new game.

What happened
Crash to desktop with the following dialog box:

Oops!
The game crashed.
The crash folder named "2019-12-29_205930" next to game executable.
It would be great if you'd send it to the developer of the game!

The error.log file indicates an Access Violation:

Unity Player [version: Unity 5.6.5f1_2cac56bf7bb6]

RimWorldWin64.exe caused an Access Violation (0xc0000005)
  in module RimWorldWin64.exe at 0033:527c4566.

Error occurred at 2019-12-29_211144.

• 0x00000001
• 0x00001218
• 0x000006e0
• 0xaaa6d4d8

Reproduction
I can reproduce the error in trade and bill windows by opening such windows.  Trade windows reproduce the error reliably, but delayed for several seconds or even over a minute.  Bill windows reproduce the error less reliably, but within a few seconds of opening the window.

I cannot deliberately reproduce the apparently arbitrary crashes, except to say that I'm extremely unlikely to get more than 20 minutes gameplay in before the crash occurs.

Attempted resolutions
So far I have tried:

• Verifying the game's files in Steam
• Reinstalling the game via Steam and deleting the AppData/LocalLow contents
• Upgrading Windows from 1903 to 1909
• Updating graphics card drivers
• Beseeching the Machine Spirit

Consolidation of information in replies

Hi,
at last i can tell you it has nothing to do with your mashine or your Rimworld installation.
I get the same error's with your safegame.
And since you don't use any mods, this is very unusual.

I think a Dev need to take a look into your safegame and why these error's happen. Because these error's lead to the crash soon or later.

I suggest to start a new colony at first.

Thanks for having a look.  I get the same problem with a new colony.

Regarding mods, I began this colony to check out RJW, but it turned out to really not be my cup of tea, so I removed it.  I had the problem both while RJW was active and after it was removed, and new colonies started since removing the mod have the same problem.

Just try out one last thing.
Delete the complete rimworld installation folder in your case it should be
C:\Program Files (x86)\Steam\steamapps\common\RimWorld
I don't trust the steam verify process.
Then let steam repair/reinstall Rimworld.

Okay, done that.  I'll see how I get on later.

No improvement from having deleted the RimWorld folder and let Steam rebuild it. Crashed less than a minute after load, in general play.
