Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Editor crashing at 83% but didn't crash before.

I am running 4.12.2 and my project opened and ran fine before hand. But from now on whenever it opens I get a crash saying

[2016.06.15-09.43.24:787][ 0]LogWindows:Error: === Critical error: === Assertion failed: IsValid() [File:D:\Build\++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 697]

About 4 hours ago the engine loaded and worked flawlessly and I have gotten no updates to hardware or software recently. I have reinstalled the engine and done numerous system restarts. I need this to work by Saturday as a I have a competition on.

What I find interesting it that there is nothing in my D drive yet it states there is?

Product Version: UE 4.12

I may have bad news for you ... I got this trouble and it was a blueprint which was broken, I had to do this one from scratch (backup files didn't worked) and now it works fine ...

Can you provide more information about when this crash occurs so that we can try to reproduce it on our end... For instance, you say your project opened beforehand -before what? Before you updated to UE4.12? Before you added a specific file? etc.

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.

  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,

Steve H.

Thanks for all this, yet i fixed the issue by moving all files to a new project and re importing them. Turns out I had two files the exact same and were causing the engine to crash!
