Engine Crash when Play in Editor

Hey folks, I’m getting a very elusive bug or error that is making my other debugging work extremely slow and tedious.

When I try to boot most levels on my team’s project, I encounter a window’s error and it crashes my engine- without a UE4 error report.

Now, the specifics:

  • This error only occurs when I play in editor, or play from a new editor window. It will never occur if I play a stand-alone game.

  • The error doesn’t always happen when I play in editor, but it has a very high reproduction rate (something around 70% of the time).

  • I don’t think it’s content related. I work on a team using Perforce, and the error doesn’t occur for anyone else. Nor does it occur at my other work-station. I also tried reverting work to about a week before I got the crash bug, and I am still getting it.

Any help or advice would be greatly appreciated.

Solved this one myself.
Seems as though I had a bum installation of my antivirus software, that was maybe leading to some false positives. Removal of the software seems to have solved my issue.
