Crash On Compile and/or Load Level

Development Platform & Builds

How It Happened:

I been building my game since 4.9, updated to 4.10 with no issues. It has been a few weeks now and I began updating the new version from 4.10.0 to todays update (12/8/2015). While updating it seemed the Unreal Editor crashed and I had to redownload the new version again from 0%.

I then tried loading my game again, at this point when loading the map or compiling any blueprint, UE4 will crash.

Below is Error Code I Get On Editor:

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

Hi DreamBotStudios,

  • Does this occur with a clean, blank project with no additional content or is it limited to one project?
  • At what point in the loading process does it crash?
  • If you remove the contents from your contents folder, do you still see the crash when you attempt to load?
  • Can you post your crash logs here? They can be found at \Unreal Projects\PROJECTNAME\saved\logs\
  • If you create a new copy of the 4.9 version of your project in 4.10, do you still see the same error or is it only with the first copy?
