I have spent all day long working on this project and my head is about to explode. This bug showed up over fifty times, after which I had to close and restart AE each time, open a new comp window, drag it to the other monitor and resize it, only to be able to use it a few more minutes, always fearing that a layer I move or anything that requires to render the frame is going to crash the extremely buggy ray trace renderer. Next time I have to do a 3D project, even if it's nothing too complicated, I'm going to use Modo 701, which is a real 3D program, unlike After Effects, which is just a fragile toy.
I am having the same issue, though today I tried something that helped a lot. I am working on a mac pro with a flashed Quadro FX 580 and a slower Quadro 4000 card, and two displays. I've always plugged one display into each of the cards and lately frequently gotten the "Ray Tracer failed to launch" error. Today I plugged both displays into the less-powerful graphics card, leaving the 580 untaxed by running a monitor and so presumably entirely free for Ray Tracing. And so far today I haven't gotten the error we both know too well. You mention being on a PC and don't mention having two cards, so this may not help you. But if you still have the card you swapped out for your 570 and can pop it in your rig it might be worth a try.
Are you running any other applications while running After Effects? Sounds like you have a second monitor. You might try disabling it and seeing if that helps. Otherwise, you may need a more powerful GPU.
The After Effects CC (12.2) update includes several changes regarding the stability and VRAM usage for the OptiX library on which the ray-traced 3D renderer depends.
Let us know how it works for you after you've installed the update.
