What are the crashes you are getting? It is difficult to understand what the issue could be without more information.
“An unreal process has crashed: UE4GAME”, should I attach any diagnostics file? If yes which one?
I use the latest version of UE (4.16.2) and after a few clicks it crashes, I tried with a new project and the same thing happens.
same problem with me, lasted 3 months.
Can you screen the Crashwindow and put the error from the output.log here (dont forget to hide sensitive data)
