Crash While Loading UTexture Data Inside PostLoad During Open Level

(User provided info)

Crash (check fail critical error) if you try to load a UTexture's data (eg UpdateResource() or PlatformData .. Mip .. Lock/GetCopy) inside a PostLoad of anything during an OpenLevel.

I only could reproduce this in a launched project via project launcher in editor. This didn't repro when packaged for me. I also couldn't generate a crash reporter window. So call stacks are unavailable.

• Open attached project
• Launch project for windows Default (WindowsNoEditor), DebugGame (or any), By The Book
• When game opens press "Tab" key

RESULT
Game crashes.

EXPECTED
Next map loads (there isn't anything in the map so the screen will appear black.
