If a sub-level is set as a Lighting Scenario in the Levels tab, calling Unload Stream Level will cause standalone / packaged games to crash.
Regression: No - Lighting Scenario not available before 4.14
Result:
Standalone window crashes with provided callstack
Expected:
The levels are unloaded / loaded based on blueprint setup
