Editor crash and memory leak

Most of them time I use code but lately I started to do things with blueprint. And sometimes editor just crashes without good reason. Also I noticed that editor eats more and more memory in time. Just now it crashed when I tried to drag and drop local widget variable to the outpu of create widget. And after restart it crashed again. This is screenshot of crash:

Here is the crashlog:

[crashlog][2]

Each time I receive the same crashlog. I even deleted everything from this widget except of this function (Arguments were deleted also) and this create widget and variable. And again, after I drag and drop it crashes. I checked, now this widget doesn’t even have any external references. So that’s why I decided to not just drag and drop but firstly to create this set node. And then connect it to output of create widget. Now it works. And after that I decided to make another test. I deleted this set node and drag and dropped variable again. It crashed.
So now I have this uasset which doesn’t depend on any other assets. So I made blank project. Imported just this asset. Drag and droped that variable. Crash.
I renamed asset to .txt and attached it. So if you can, you can study it closely (don’t know if it is possible)

Also here are some memory logs I made yesterday. I had again a lot of memory consument (1.8GB for a simple project). And after restart there were only 1GB:

[1.8GB][4]

[1GB][5]

I renamed them from memreport to txt. I made them with memreport -full.

I noticed last hour or more my computer was very laggy. I looked into task manager and now editor has eaten 4GB of RAM. That’s a lot for me. Here is memreport which I got with memreport -full

[4GB][1]

It was in the same project. Project is just a third person template with a little bit of my blueprints.

Hi funbiscuit,

If you go to the filepath \Unreal Projects\PROJECTNAME\saved\logs, can you upload the .dmp and the logs located there to here? Additionally, can you post your dxdiag?

I added everything what was in that folder to file. dxdiag is also there
logs

Have you changed any of the folder structure for your project? Renamed any folders or moved assets around to new locations? Additionally, is the memory leak occurring while the editor is open or does it occur after the crash?

I don’t think I changed structure of the project when I got crash for the first time. Later, as I said I copied this widget to empty project without all other assets.
I have this leak almost all the time. I just don’t notice it sometimes. Maybe it doesn’t crash because of leak. It just gets very laggy.
For example now I opened task manager and editor eats 2GB. Project is the same.

Can you send me a copy of the asset that is causing this error? I will be happy to test on my end and see if I get the same results.

I attached it to the first message (asset file) i renamed it ro txt to be able to attach. Just rename it back to uasset (it is called questnodewidget.uasset.txt)

Hi funbiscuit,

I was able to reproduce this crash and have entered a bug report, UE-13595 to be assessed by the development staff.

This crash was fixed in this github commit. Thank you so much for your detailed bug report. This fix will be in the 4.8 binary release.
