4.8.2 Unstable, constant crashes

After update to 4.8.2 my Unreal has been very unstable, crashing all time. This usually happens after I compile a blueprint or after launching my game. This did not happen before this update. editor does not crash every time I launch 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 crash was after launching game.

To be clear, if I start editor again and launch my game there’s a chance it will run and a chance it will crash 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 report! I’ve assigned a member of support staff to look into crash for you, and they’ll post here if they have any questions for you. good news is that it appears to be same crash most of time, so hopefully only one issue is causing it.

If you’re willing to share 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 forums:

Thanks!

Hi pzea,

I was able to track down 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 forums with a link to your project that’s uploaded to google drive, dropbox, etc.

Thanks,

.

Hi pzea,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing issue you reported, please respond to this message with additional information and we will offer further assistance.
