I can confirm this very same issue. It is Elementor Pro, with all the latest updates.
It comes up with:
Translations
New translations are available.
and when I click on “Update Translations” button below it shows me…
Update Translations
Updating translations for <strong>Elementor (en_GB)</strong>…
Translation updated successfully.
Updating translations for Force Update Translations (en_GB)…
Translation updated successfully.
Go to WordPress Updates page
Then I go back, and no amount of cache clearing, or switching it off etc does fix this. I have tried everything, including “Force Update Translations” plugin etc.
Nothing worked. Elementor Pro issue that needs a fix. Very annoying as comes up with constant update notification that can’t ever go away, please fix it.
