To expand on @DarioTD's comment, a more appropriate fix would be to replace line 419 with:
_loopDev=$(udisksctl loop-setup -r -f "${_isoFile}" --no-user-interaction 2>&1 | grep -oE "'.*'" | sed -e "s/'//g")
and remove line 420. This will determine the correct loop device automatically by reading the error printed by udisksctl. I'd recommend adding this change to the PKGBUILD so it actually works until someone can figure out what is causing the error.

You apparently need to be a member of the
disk
group to mount a filesystem as an otherwise unprivileged user.And log out and back in again.
