This happened after building my project in VS 2015. Now I cannot launch the editor for my project; it just prompts this crash. I’ve tried removing the -Zm98 command and rebuilding the project, but to no avail.

I’ve attached the log to this post.

Hey pythonxz-

While the project doesn’t close/crash for me, it did hang during the launch process. This has been reported as UE-33408 and I will comment here with additional information if a workaround/solution is discovered.

Cheers
