So, today, after several rapid PLAY->CRASH->RELOAD->PLAY-CRASH cycles over a half hour. I eventually noticed that, somehow, my setting under "play" was "Vulkan". Not sure why or how it got set to Vulkan, but changing it back to DirectX has solved all the crashing issues...

Still have the split-player blackout issue.
