@tydynrain, you probably won't like this answer, but there's something tainting your environment causing the build to fail. The binaries are still building successfully using a docker clean room environment on stateless build nodes.
My only advice is try getting the package to build in a docker container since there may be a common thing you're changing on your system, even on new installations, that's causing the failure.
If you need a starting Dockerfile that sets up the makepkg.conf file for you and dependencies, you can use the one used for CI in the cloud here: https://github.com/damentz/liquorix-package/blob/6.2/master/scripts/archlinux/Dockerfile. The GPG commands at the end expect that you define your local signing key, so maybe you can omit the gpg import and conf file changes for purposes of testing your build.
