I see the problem but I do not have a fix. Not many EndevourOS (or Arch) users on this forum but maybe someone will respond.
I see from your specs that the display is Wayland. That might be the problem although the plugin was updated for that
see: https://yingtongli.me/git/gimp-xsanecli/...89755e7b95 Check that you are using the latest plugin.
Is XWayland also installed ?
Otherwise, the usual checks.
In a terminal start xsane - does it work ?
This is my usual wireless printer/scanner rather than that other USB scanner, which is easier to set up. The wireless scanner opens up xsane as (warnings but it works)
Start Gimp in a terminal gimp --verbose and when open File -> Create -> Xsane via CLI Look for any error messages in the terminal.
You might be better off asking in the EndevourOS forum.
