Crashing randomly in editor

Development Platform & Builds

I keep getting random crashes when trying to play in the editor.
They can happen anytime from first launch to after an hour of work.

Been getting 10+ crashes daily, really big problem here happening for a few different projects.
I’ve read this post reporting it to be a bug that should have been fixed in this version?

No custom FBX models in play at the time of the crash, nothing referencing actors to do with those models either.

Crash throws up this error:

We apologize for the inconvenience.
Please send this crash report to help improve our software.

I’ve had 5 crashes in 20 minutes! Really getting frustrated here trying to release something for a living. :frowning:

Hi Daverm,

I have generated the bug report JIRA [UE-7067] for the crashes you are experiencing. However, the developers are currently off for the holidays so it may take a while to get to this particular issue. In the mean time, it would be helpful if you could also supply your DX Diag as well as the following logs:

“UE4.log” Located: Engine\Saved\Logs\

“ProjectName.log” Located: ProjectName\Saved\Logs\

Thanks
