That is quite old, containing the date 20250109, January 2025, and App Lounge came on a lot since then. It will be unlikely to work correctly.
The challenge now is to find why it didn’t update.
FYI here are the builds published since (but do not try to download and install any of these, they are Fresh Install with Format data builds, identified as such with prefix IMG-).
If no updates are showing in the Updater please try this:
Settings > Apps and notifications > See all … apps > 3 dot menu top right > Show system > Updater > Storage & cache > Clear storage | Clear cache
(Updater is Mises ä jour du systême aka Gestionnaire de mise ä jour aka org.lineageos.updater)
Restart the phone and tap the Updater Refresh button quite a few times. If you get a list of updates, install the latest (no need to apply the updates incrementally).
Only if the above has no success
From the already linked thread @piero offered this advice

You are in a similar position, but you don’t have to change Android version.
You just do a manual Local update using official source Builds – Django REST framework and choose and download onto the phone the latest build which shows on the line reading
