1. Make sure you have an expired license (or hardcode the check to say failed)
2. Start up the Test Suite: EditModeAndPlayModeTests\OnDemand
3. Run the test "GetArtifactHash_ByBlocking_ReturnsValidHashAndProgress"
4. Notice the test hangs forever.

Additional info:

Main Process hangs on:

completionHandler.completionEvent.WaitForSignal(); inside OnDemandScheduler::WaitForImport
