Crash on starting any game

[Wox77]

So, the game opens fine. I select a game (introduction, or a custom one), it plays the cutscene fine, and then as soon as it hits the game screen proper, it immediately crashes and brings up the following:

Renderer.cpp:930: void__cdecl
proxy::video::Renderer::submitCommands(void): Failed to submit to queue. -4 VK_ERROR_DEVICE_LOST.

I have validated files several times (always comes back as 100% validated) and put the graphics back to the default. I have also updated all my drivers, and rebooted the computer. Crash still occurs.

Please advice.
