Not yet, I spent time figuring out weird errors I was experiencing on Arch in the first place. I built a 2.27.3-1 package (I will attach it here) and I can now investigate the problem you were interested in.
I tried to install this on my Antergos. There are file conflicts with the existing snap-confine package. Can you provide good steps to do this for testing? I don’t want to bork my system (as the arch wiki suggests forcing this may bork it).

/usr/bin/ubuntu-core-launcher is owned by snap-confine 2.26.1-1
I’m trying to resolve that issue. The problem is that the TU (trusted user) that maintains the snapd package became non-responsive and I cannot commit to the community repository directly.
