I am developing a game in UE 4.27, using a custom build from source of the engine. I am 3 years into development and the game has been shipping for 2 years in Beta, as I continue to refine the product. Two days ago, my system froze when my VR headset battery died, requiring a reset by holding the power switch. After restarting, the packaged (Shipping) build would no longer run: just a black screen, and “not responding” in Task Manager, with a unchanging 542 MB of memory being used by the game .
I have cleared the shader caches (NVidia DX) and DerrivedDataCache in both the Engine and in the project directories, I have rebuild the engine from source and the project several times, recompiling 10,000 shaders.
An installed copy of the game on my computer, as well as the (Shipping Packaged) version in the project directory BOTH fail in the same way, leading me to conclude some file common to both has been corrupted.
I have removed all VC folders from the build directory, recreated VC project, and rebuilt, but the issue persists.
Running from the editor, either in a standalone window or in the editor works fine.
Can anyone please suggest anything I might try to identify and correct the source of this system corruption?
TIA
