Map update error TopoActive Europe 2022.10

I was updating my F6X Pro Solar but then my son took the charging cable (he didn't know that I was updating) to charge his own Garmin watch. So the update process was aborted. Later, when I tried to update my Fenix again, I only get error message "There was an error installng the update". I tried with different computer -> same result. I believe the problem is in the watch.

Any ideas how to recover from this?
