"After Effects has stopped working" every few minutes during render

I'm working on a green screen replacement and during render, within a fifteen minutes, windows will pop up that After Effects has stopped working and then the program closes. I've been rendering to a TIFF sequence so that i can start back where I left off, but I have 40min. of footage which will take an estimated 80 or so hours to render. So having to start it again every fifteen minutes isn't really an option.

The comp (From top to bottom)

Light Wrap: Baked Background plate with gaussian blur, channel blur, and set mattes

KEY: A pre-comp of several layers source footage with their own instance of key light. For the comps I need to render it varies between 2-3 layers. Visibility is off and serves as a matte.

Despilled footage: Has color balance, lumetri color, advanced spill suppressor, grain removal, and unsharp mask.

Shadow: Footage crushed black using levels, blurred, and moved to the side

Background: Baked background plate

I'm running After Effects 14.2.1 on Windows 10. Intel i5 3.2GHz, 32GB of RAM.

Any help is greatly appreciated.

check you project settings, are you using the GPU to accelerate the supported effects? if so, turn it off (software only) and try again.

Dang. sounds like a nightmare. I just had a keying project that that crashed each render due to bad GPU on some workstations. my guess is that it's Lumetri that failed my GPU. just to make sure, we're talking about this menu:

other than that, my advice is to try to isolate your problem. I take it this happens regardless of a specific frame? what if you disable a certain effect? see where it's breaking.

another advice is to try a different Ae version. save a copy as CC (13) and try 2015.3 if it works better.

maybe reset your preferences might do the trick

try rendering to another drive

try different format if you can

try prerendering certain precomps

I just rendering the next comp I noticed I still had Chrome open, closed Chrome and AE Crashed. While I know that's not the case for the other times I'm wondering if it could be related to the real issue.

Was looking good for a while, finished one render, went on to the one and After Effects crashed in five minutes.

Try removing any screen preblur from your Keylight effects. I've seen a number of people have issues with preblur in the Keylight effect causing crashes.

What codec is your footage with the keys? If it's native files from the camera (and your camera shoots into a compressed H.264 variant), that has also been known to cause occasional problems. Try transcoding your footage into DNxHD or Cineform (or other similar intermediate codec) and then key that.

The footage had already been pre-rendered to DNxHD as well.

Well, crap. The usual suspects seem to be dealt with.

What happens if you completely power off your computer, then power it on, open nothing but AE, and try rendering? (Also, check what programs are set to auto-start when you reboot).
