Had this issue before with 4.7 P3 and re-installing seemed to fix it but no luck this time.
Help? :frowning:

Hey Brucey540 -

I have entered a bug report in for this issue, but I need a few files from your crashed project to help us find a solution. The more files we have the better and faster a solution we can get.

I need a copy of the diagnostics.txt, minidump.dmp, [ProjectName].log which can be found at:

 C:\Users\[UserName]\AppData\Local\Microsoft\Windows\WER\ReportQueue

Thank You for your help -

Eric Ketchum

Hi Eric, Thanks for the response.

Note this issue is also occurring when launched as a standalone game from the editor.

Regards,
Rob

Hello everyone -

We are actively looking at this particular issue, but are not having a lot of luck internally reproducing the crash as it is described. So in order to get as much information as possible, I am asking anyone on this and multiple reported threads of this issue, to please follow the steps below and then attach the Error Report Files here. You can find the Error Report Files of diagnostics.txt, minidump.dmp, [ProjectName].log at:

C:\Users[UserName]\AppData\Local\Microsoft\Windows\WER\ReportQueue

Go to the Engine Install Location (usually C:\Program Files\Epic Games\4.7\Engine\Binaries\Win64\ OR C:\Program Files\Unreal Engine\4.7\Engine\Binaries\Win64).

When in the Install Directory, Shift-Right Click (with nothing selected) and Open Command Window Here

In the command window type:

UE4Editor.exe “[ProjectPATH]” -onethread

Once the Editor opens, proceed with the steps used to crash the engine previously (Create a Movie from matinee).

Remember to submit the Crash to Epic via the Crash Reporter that pops up, include the following in the Description:

One Thread Test per Eric Ketchum

Finally Zip the files mentioned earlier and post back here with your Machine ID (from Crash Reporter) and the Log Files attached.

Thank You -

Eric Ketchum

Hello Brucey,
Do you have an oculus plugged in? I was having this same issue, and resolved it by unplugging the HDMI and USB cables before I ran the recording. Hope this helps.

Unplugging the Oculus HDMI cable fixes the issue. Weird but an easy solution!
