Editor 4.4 crashes when duplicating nodes

UE4 crashes when I try to duplicate (Ctrl+W) a node on the material editor. This is the message that appears on the UE4 Crash Reporter:

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

Thanks for advance!

Hey-

Which node did this occur with or have you noticed it with multiple nodes? Was the node attached to anything when you attempted to duplicate it? Iif you could provide your logs as well it would help us investigate this further.

Thanks

Hey ,

I’ve uploaded a screencasting showing the moment when UE4 crashes:

I didn't tested if this occurs when I select two or more nodes to duplicate. As you can see at the video, the node is not attached to anything. Finally, where I can find the error log?

Thanks,

Hi ,

Thank you for the crash logs, can you post the dxdiag as well? This can be found by going to your windows searchbar and type in cmd. Select the command prompt application, then type in dxdiag into the screen that appears. Press Enter. When the dxdiag appears you can save this to a text file and upload that here. We have several other users reporting this and I would like to see if there are any similarities between the systems that may be the key to this crash.
