Packaged game crashing on Open Level calls

GotNoBones · April 21, 2017, 7:19am

My game works without any runtime errors in the editor, but when I package the game it will crash about 30% of the time when I change the level. Below is the crash report that I get when it fails.

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

Hello GotNoBones,

The Access Violation error means that it’s failing due to not finding either a reference or asset that it’s looking for and requires to continue. As such, the first thing we should check for would be to ensure that there aren’t any missing files that didn’t get packaged. To do this, can you look through your log from the packaging process? This can be found in your project’s directory under Saved/Logs. I’d suggest searching for the word Warning and Error to see if there are any messages that could point to what the problem is. If you aren’t able to diagnose it yourself, please upload the log file.

Edit: In the future, in cases like this where you’re unsure if the issue is actually a bug with the engine or something that this wrong with your project, please post issues like this in the Packaging and Deployment section. I’ve moved this question for now.
