Crashes during render (deliver page)

I'm starting to see crashes when trying to render my full project now. The project is more complex than it was before, but I think the only tool/process I'm using now that I wasn't using before is having more than one MediaOut node in Fusion, and using more than one input on the color page. I'm not sure if that's related, but it seems like a likely suspect. I am also still using 17.2.2, so I'm curious how likely it is that updating to 17.4.2 could potentially make a difference here. I want to avoid that update if I can until I finish this project, so other work arounds are very welcome as well.

...having more than one MediaOut node in Fusion, and using more than one input on the color page...other work arounds are very welcome as well.

Did you try a test render on a duplicate timeline where you remove that potential cause?
