Unreal Engine crashes when opening context menu

Joao_Hanson · December 5, 2017, 9:13pm

Since last week, while I was still working on UE 4.17, my Unreal Engine started to crash.

I open my project normally, and like 5 minutes or less after I start working, if I open a context menu it crashes. Then if I open a project again it will crash on the first context menu I open. After that everytime I initialize the Unreal Engine it will crash instantly, and if I try to open a project directly it will freeze as soon as it starts. And it keeps like that until I restart my PC, then it starts all over again.

I will leave an Unreal Engine crash log and a Windows crash log here so you can help me.

Same happens to me.
But only when I have iexplore, crhome or mozilla open.

Same happens to me.
But only when I have iexplore, crhome or mozilla open.
I need restart to use UE4 again.

Now that you’ve pointed it I noticed that here it only happens when chrome is open too. But I really need it to be open so I can keep track of the tutorials, the classes and so on.

After working on my project for about half an hour without any of these programs open, it crashed anyway, just took longer.

I’m having the same problem…

Same on UE 5.0.3
