Dear Greg,
Thank you for the reply. I will reply in blue.

 - where are you syncing to and from?
I am syncing local folder "Downloads" in my Fedora 43 to another 128GB SATA
SSD install in the same pc. Also trying to sync to another external drive
with 2 128GB SATA SSD installed in external ssd enclosure.

  - what version of unison (on both computers, if remote is involved)?
Unison 2.53.7 (ocaml 5.3.0)

  - the error as text rather than an image
I don't know what it means

  - the results of you trying to simplify by syncing locally, by
    disabling the watcher, and by using the CLI, if you are using the
    GUI.
The syncing is done using Terminal, unison work && unison ~/Downloads
/run/media/jq/128\ WESTERN && unison ~/Downloads /run/media/jq/128\ KINGSTO

  - what changed yesterday about your OS :-)
Nothing change on the OS itself. I just went Gnome Disk Management to "Edit
Mount Options", turn off "User Session Defaults" to enable "Mount at system
startup", then on "Identify As -


That is all I have done =F0=9F=98=80.
