Can't log onto desktop app

I was editing a score that's in two different files and saved them pretty much simultaneously. After this I accidentally shut both down. Now I cannot open either as MuseScore desktop app says I need to login. When I click login, it opens up browser (Chrome) and it says I'm already logged and should be able to just jump onto the app. When I open the app, the login prompt persists and trying to open scores doesn't work. The first picture has options in Finnish but it says I need to login or sign up as a new user to view the score.

EDIT: Problem solved itself
