Unreal 4.12.5 keeps on crashing

Every time I open my project it keeps crashing. I’ve noticed it only happens when I am in the blueprints section and most often when I am searching for a component. Here is the latest crash report if it helps. I hope someone can help me with this.

Hello,

  • Could you please cause the crash to occur again and provide the logs from your project’s Saved->Logs folder?
  • What steps are you taking when this crash occurs?
  • Are you able to reproduce the crash in a clean project?
  • Does this crash also occur if you upgrade a copy of your project to 4.13?
3

Here is the crash log. The crash happened when looking for a component on any blueprint graph and I was able to reproduce the crash in a new project. Upgrading to 4.13 didn’t fix the problem either.

4

If you were able to reproduce the issue, could you please provide a list of detailed repro steps?

5

When I go into any blueprint graph and look for a component, whether I right click on an empty space or drag off from another component, and I type in the search bar and start scrolling. The amount I have to scroll is inconsistent before it crashes.

6

Could you provide a brief video of your process to reproduce the crash? Following your repro does not produce a crash on my end, so it’s possible that I am missing something.

7

I can’t attach the video because it is 1 mb more than the maximum, but on further testing, I found that the crash only happens on my laptop scrolling with the trackpad.

Try uploading the video to YouTube and making it private if you are concerned about privacy. You can PM me the link on the forums: https://forums.unrealengine.com/member.php?160394-Sean-Flint

Also, we’ve tried to reproduce the issue on our end using a laptop trackpad but haven’t been able to do so.
