Hi @Photon89, is there a specific release of Arch which fails the build?

[Photon89]

Unfortunately, I only know that the breakage happened between 2019-03-12 and 2020-06-14 and is still present, a large time window...

Problem is now solved. Huge thanks to @Photon89 for pointing me in the right direction.
