4.8.2 Unstable, constant crashes

Development Programming & Scripting Blueprint
, , , ,
1

After the update to 4.8.2 my Unreal has been very unstable, crashing all the time. This usually happens after I compile a blueprint or after launching my game. This did not happen before this update. The editor does not crash every time I launch the game or compile a blueprint, but there’s always a good chance that it will.

Here is my dxdiag: link text

This is an example of what I get when it crashes. In this instance the crash was after launching the game.

To be clear, if I start the editor again and launch my game there’s a chance it will run and a chance it will crash the editor. Same with compiling a blueprint. So it’s not that I did something weird in my blueprints that is causing it to crash every time I launch or compile. Sometimes it crashes and sometimes it doesn’t.

Hey pzea,

Thanks for the report! I’ve assigned a member of the support staff to look into the crash for you, and they’ll post here if they have any questions for you. The good news is that it appears to be the same crash most of the time, so hopefully only one issue is causing it.

If you’re willing to share the project with us so we can take a look here, that might be helpful. If you upload it somewhere, you can either post a download link here or send it to us privately via the forums:

Thanks!

Hi pzea,

I was able to track down the crash in our database, but we’d still like to get your project so that an engineer can reproduce in house.

Now that I’m working on this, you can PM Me on the forums with a link to your project that’s uploaded to google drive, dropbox, etc.

Thanks,

Matt W.
