I have encountered the bug: UE-51929
I’ve gotten this bug several times over the past week or two. I am on UE 4.20.
Everytime I’ve gotten this bug, it happened after playing the game in editor. It seems to happen both when using the in-editor viewport, as well as with a detached separate viewport. The map loads at least partially in the background, then I hit the crash. I’ve gotten this when I hit play then focus on other apps, as well as just hitting play and touching nothing, just waiting.
When I hit this bug, I’m attached with visual studio, running as development editor. Also, this is on Windows 10, with VS 2015 if it matters.
Since this is supposed to be a question, has anyone found a fix for this bug? It seems to be unrecoverable.
