Hello, all!
I wanted to provide some updates for future users:
It seems that my issue was related to available space in my /tmp directory.
Since I'm using an EC2 instance, I was able to resize the /tmp folder to 1TB (or 2 TB, I can't recall exactly) and run the code successfully.
For any future reference, my EC2 setup was utilizing a c4.8xlarge instance with a 2TB volume attached.
Once I resized the /tmp folder, the run took ~1 week to run but did finish successfully.
