Possibly related  FS#76792 , although the problem there seems to be between 252.2-3 -> 252.3-1. Can you try the workaround mentioned in that ticket?

In your case, the problem seems to be between 252.1-2 > 252.2–1

Either way, you're going to have to debug this issue yourself (or with help from the forum) because you haven't supplied enough detailed information to identify an Arch packaging bug. This bug tracker is not for support.

If you are *certain* that systemd is the cause, you can use git bisection [1] to identify which systemd commit broke it. Also please keep in mind, if you are downgrading other pkgs (e.g. kernel, mkinitcpio) then systemd might *not* be the culprit.

git bisect bad

3ec3ae68d2cea32461d779645a737d57160631bf is the first bad commit

basic/strv: add optimizable version of strv_push/consume/extend

This will be helpful in cases where we are repeatedly adding entries
to a long strv and want to skip the iteration over old entries leading
to quadratic behaviour.

Note that we don't want to calculate the length if not necessary, so
the calculation is delayed until after we've checked that value is not
NULL.

> git bisect bad

???

You have to keep on bisecting (git bisect good, git bisect bad, etc) until it tells you which is the first bad commit. This is all documented in the man page [1]. Please be *very* careful about posting wrong information upstream...otherwise you are just wasting developer time.

Closing for now. You can request for this ticket to be reopened if you reach a conclusion via the forum.
