Snowman somwhow it worked for me after changing my windows display language to Norwegian from english, then back to english again. Launcher updated and all good
Sivert try doing what Simen said, it works for me now
I got the same issue as Sivert after update today
The game started working for me yesterday after a few hours of troubleshooting, altough im not sure what fixed.
What i did:
Updated to latest windows preview version
Windows language changes
After these to steps and all above the launcher suddenly updated and all was fine, could be a coincidence. I am also Norwegian
