Game runs in Editor, crashes on startup after build. "Access Violation (0xc0000005)"

Questions & Answers
1

Hello, as the title states the game runs flawlessly in the Unity Editor, but crashes on startup when I try to run it after it’s built. The problem only started after upgrading to Unity 5, there never was a problem when running the game when built with Unity 4. I’ll post a bit of the error log and the stack trace as well.

One thing I noticed that’s strange in the error log is that physical memory and paging file both only have 0 MB free. Here’s a bit of error.log…

space_combat_apr_19_2015.exe caused an
Access Violation (0xc0000005) in

And here is the stack trace from output_log.txt…

**** Crash! ****

Any help is greatly appreciated, thanks!

With help from wiliz and NCarter from the IRC chat, I was able to solve my own problem.

I learned that the game would crash when it tried to load a scene with any UI objects that had any component with a material set to none. Changing all the UI elements to have any actual material prevented crashes (but also screwed up the looks of the UI).

The fix was to go into Edit > Project Settings > Graphics and under “Always Included Shaders” make sure that it contained UI/Default and UI/Default Font. Mine didn’t have either of those, but when I added them all the crashing problems went away and the built game ran flawlessly.

Hey everyone, the fix for this is planned for a 5.3 patch, so hopefully by 5.3.1 it will be fixed.

The fix is to load the default shader (the one that makes things pink) so you will still have to include the shader the way you currently do but this will not cause a crash.

For those like me that found this solution not to work i would suggest to check if you are using The Audio spatializer. Both editor and build would crash for me (from output.log it seems i lack the audio plugin??? it makes no sense). It has been week but i never noticed because i looked for errors only in the editor logs. Now i’m running my game for half an hour and there are no crashes.

Hope it’s helpful, it did seem to solve my problems.

edit:oh yes, using unity 5.5.0f3, very satisfied so far.
