having the same issue with the charger bought 2022, which works fine so far. After firmewareupdate at 21.April 2025 my product shows same behavier as descript in several posts.
Victron energy statet in their posts this is a HW issue and is not linked with the firmeware update. Startet a warrenty request, will see how fast they will react here in Germany. Might be more causes upcoming soon…
