Problem with sync on an ARM Mac

Hi, long time Unison user here on Mac and Windows. I have a setup for more
than 10 years now to backup and sync my work computer. It goes like this:

   - A whole "Work" folder from my desktop Mac (Intel iMac, drive is APFS
   SSD, MacOS 13.6.6) is synced to a folder on a 2 TB external SSD drive
   (formatted as APFS). It uses Unison 2.53.3 with ocaml 4.14.1
   - I then sync a subset of this folder (some subfolders etc.) from the
   external SSD drive to my laptop (MacBook Air M2, APFS SSD drive, MacOS
   13.6.6) to keep with what I'm currently working on. It uses Unison 2.53.4
   with ocaml 4.14.1.
   - I go from iMac to laptop and back using the external drive, syncing on
   each machine to update with what I've done on the other.

No problem syncing between iMac and external drive, but when I try to sync
between external drive and laptop, I often get the "No archive files were
found for these roots" error. I have to delete the archives files in
Library/Application Support/Unison, rescan the whole thing and then it
accepts to sync the small changes. Then it works for ~24h before
complaining about the missing archive files (even if I only worked on the
laptop in between, meaning the external drive was synced with the laptop
last, next day I sync again with the laptop, I get the error).

How can I help get this problem solved? It's hard to keep using Unison if
it entails a ~1h sync and rebuilding archives every time I sync with one of
my two computers. I posted this on Unison Github and was pointed to this
mailing list with the hint that "My Mac keeps changing paths" but I don't
know what that means or how to avoid it?
