Hi Efrye,
You’ve stumbled upon the fact that we are starting to roll out German localization for the launcher. This first part of the roll out only the certain aspects will be translated with more coming in the future.
If you’d rather stick with English you can change this on the sign-in prompt. There’s a little globe icon in the top right corner. Just choose English from that drop down and you should be good to go!
If you are running Windows and you don’t want to default to German in general, make sure you’ve changed the following “Format” setting to English.
