That all seems normal and recent enough. I don't have any other ideas.
You can try running with --ostree-verbose to see if you get more info.

That said, "Writing content object" in ostree happens when writing the
objects to the repo's temporary storage. That would be in the
tmp/staging* directories in /var/lib/flatpak/repo or
/home/yvan/.local/share/flatpak/repo. You might want to look at the
permissions of those. Alternatively, you can just wipe the
tmp/stagiing* directories and you'll drop objects that you've
downloaded but not committed and start fresh.
