As @eskimo pointed out, by removing some resources we narrowed it down to the background file. Without it the build goes fine so, for now we'll just skip it.
The odd part is that the same setup is in several machines, but only that one had an issue with said file (we event checked the shasum of it and it was fine).
BTW, It is also the file used in the field "background-darkAqua".

background and background-darkAqua are for the installer wizard. They set up some login on the lower left corner. Each of them correspond to where the user runs the installer in light or dark theme.
Also happens in a Catalina machine, same xcode and CLT version though.
Hi @eskimo
I just mailed you the crash report.
Thanks!
