Unexplained Hurdles when compiling the linux kernel for arm cpus

hi gang

so I've been working on this fully arm based homelab project and one of the things I decided to do is compile myself a Linux kernel with specific adjustments that suit my needs after building my own dtb.

I kept running into errors and went into the troubleshooting rabbit hole for 3 days to no avail until I decided to try it In a different distro (Ubuntu) and it just worked?!

I know I'm being very vague here but I'm curious if anyone faced a similar issue like this and I'd love to hear why
