Software version 14.15 messed up my Vivoactive 5

Hi! My Vivoactive 5 just notified me of the 14.15 update, and then it started the download process. This process took much longer than the usual updates, and when it was finished downloading and installing, it said version 13.19 (!), and everything is in English (my watch was set to Norwegian), and my custom watch face disappeared. I have tried going into the menus to change the language back to Norwegian, but English is the only option. Nothing else. I have tried running the update process manually again after this, but it still takes a long time (15'ish minutes), and everything stays in English and version 13.19.

What to do?

Best regards,

Eivind
