Editor freezes when opened twice

Lately i have frustrating freezes with the 4.13 Editor.

As soon as i open a second instance or start a StandaloneGame next to the editor, the first editor freezes…
I can recreate it with two empty projects - any ideas where this problem might come from?

Hello FATBACHELOR,

Were you able to do this without freezing in previous versions of the engine or is this the only version you’ve tried this in? When the editor freezes, does it provide a crash report or any type of error message? Can you upload the log from the first instance? You can find it in the project’s folder under Saved > Logs. Are you using Windows? If so, could you provide your dxdiag information?

We haven’t heard from you in a while, FATBACHELOR. Are you still experiencing these issues? If so, could you provide the information I requested in my previous comment? In the meantime, I’ll be marking this as resolved for tracking purposes.

Hey Matthew,
sorry it took so long. I moved to another Computer - with the same results. The Project was also recreated just with imported Blueprint and Assets. The Editor still freezes sometimes - cant say when. The Editor does not create any log files upon freezing - the log file was 2 hours old when it happened today. Both computers are Windows 10 and it seems to be occuring after the Annivesary Update ( didnt notice a problem beforehand ) would you still want to see the dxdiag? Any other locations to look for a Log file? Thanks

*The freezes occur on the Editor that IS NOT in the foreground/focused. It doesnt matter if im browsing the web or playing the game in standalone

Getting the dxdiag information would still be useful as it could be GPU, RAM, CPU, or driver related, as there could be parallels between the two PCs. It’ll also be useful for me to get as close as possible to your setup when trying to reproduce the freezing activity.

As mentioned prior, do you get any error messages when the freezes occur, even if they’re from Windows? If you do get one from Windows, we could use the Windows Event Viewer to get more information.

Okay -link text
No error messages - it just freezes and everything is unclickable - nothing specific in the task manager too…

You also mentioned that now that you changed computers and created a new project that the freezes are still occurring “sometimes - can’t say when.”. Does this mean you don’t have any specific reproduction method anymore? Does the old method still work with 2 empty projects as previously stated?

Hey Matthew, somehow it seems to be related with the project itself - as working with something completely new didn’t cause any problems.
If i find anything specific in that project i will report.
