[Windows] Screenshot crashes the game

[steadyfield]

The game crashes when using the in-game screenshot command (F5).
I'm using the last commit b7bd94c for build. This screenshot crash problem did not occur before 0235b1e, including 0235b1e.

in engine.log, there is only one line related:
Setting state from prevent no to prevent no: Cleanup
