Fatal error when pausing and sleeping when using Launch Windows Game

When using the pause command in a launched game and putting the computer to sleep it causes the fatal error "GameThread timed out waiting for RenderThread" when logging back in and resuming work on the project. Unable to test in 4.19 since this had to be tested on a home PC.

1. Load up a blank project
2. Launch project as a Windows Game
3. Open the command line and type in 'Pause'
4. Alt-Tab out and/or press the Windows key to put the computer to sleep

Results:When you load back up and login you get the crash error "GameThread timed out waiting for RenderThread"

Expected: The game is still launched and you type in "Pause" again to un-pause the project to resume work.

Notes: Due to Sleep being disabled by IT this had to be reproduced on a home PC.
