Crash with Access violation - code c0000005

Development Getting Started & Setup
, , ,

After working in 4.4.3, my project crashed and now the editor fails to open, even after 3 attempts at de-installing and re-installing the entire engine. I have removed all projects from the project folder.

Last time this happened, I pressed the verify button for 2 or 3 days. Eventually a patch uploaded and it worked. I have tried this for over a week and it still crashes when loading the editor.

The following error message appears… Please help.

Hey NitroGraphics,

Are you seeing this crash with all projects, or just with one? This sort of crash is often the result of the editor automatically opening a project that is corrupt. You can avoid that by opening the folder of another project and opening the .uproject file. If your project is corrupt (usually just a corrupt blueprint or corrupt asset), you can remove assets from the project folder and attempt to open the project again - there may be errors, but if you remove the corrupt asset, you’ll be able to open the project again.

Jonathan,

Thanks for your reply.

This crash report is with every single project, even starting a new blank project. I have removed all files from the “Unreal Projects” folder. Does this mean that the default empty project template that is shipped with the engine is corrupt? even after re-install?

I can’t imagine your install of the engine is damaged if you’ve reinstalled it. Can you give me your crash log, dmp file, and dxdiag? This thread explains how to get those.
