UE4 intermittent crashing while working and closing project

Hello,
been running into a series of crashes recently with a project I was working on. The scene was last opened about a week ago, and all of a sudden I’m running into some intermittent crashing. I’ve had it crash a few seconds after opening, and other times it crashes only when exiting. The project has been in the same engine version throughout. Before these crashes this week, I never experienced one previously with the project that I can recall.

Here is the crash log:

Access violation - code c0000005 (first/second chance not available)

Hi Flakked,

Can you provide more information about when this crash occurs so that we can try to reproduce it on our end? Do you recall the last work you were doing before the crashes began?

Also, please provide as many of the following as possible:

  1. Your dxdiag (Windows Start Button>(search “dxdiag”)>Launch dxdiag>select “Save all information”>attach text file to your post.)
  2. If the Crash Reporter window is present when the crash occurs, select “Copy Callstack to the Clipboard,” and paste that information in a document and add to this post. Be sure to hit “Submit” on the Crash Reporter pop-up to send the Crash Report to Epic (This Callstack will include your machine ID which we use to identify your crash on our Crash Reporter web site.)
  3. “UE4.log” Located: Engine\Saved\Logs\
  4. “ProjectName.log” Located: ProjectName\Saved\Logs\

Providing this information and appropriate logs will help us track down and isolate the source of the bug as quickly and efficiently as possible.

Thanks for your cooperation,

.

Hiya ,

I actually figured out what was causing the crashing: Turns out it was a recently installed screen recording program that was causing the conflict. (specifically plays.tv in this case) After disabling it, Unreal appears to be fine.
Here’s the extra info in case you’d still like it:

  1. DxDiag: link text

  2. Crash Report: link text

  3. No UE4 log present for some reason. (double checked to make sure I was looking at the correct engine version)

  4. Project Log: link text

Hope this helps!

Glad you were able to isolate the cause of the problem and thanks for posting the solution so other users with the same screen recording program can benefit! We use Snagit and Fraps here, which have no conflicts as far as I’m aware.
