This is correctable. See How to fix a split Fusion Drive - Apple Support for reference. There are manual methods to correct it as well.

Bootcamp Assistant tells me "An internal error has occurred", Tried installing Mac OS 10.15.3 to both SATA and PCIe storage volumes but did both installations produced the same output.

If you install macOS on both physical drives when they are split, BCA will not support such a configuration.


Why is Apple being petty?

This is a software issue. 😉

I'm also having the same issue. I have an iMac 27 inch 5k retina late 2017, which used to have a fusion drive originally, but i had the hdd replaced with an ssd hard drive. I'm including a snapshot of the command lines mentioned by Loner T.

Can you start a new discussion to avoid confusion with OP?
