Greetings Spartans!
I successfully downloaded the Halo Infinite campaign from the Xbox App today. My primary language is german so the game was installed in german. Here is my problem: I want to play Halo in english. I have already found the “manage game” section in the options menu but I can’t install new language packs from here. As I select a new pack it says “will install”, but after I press “apply” the panels go grey for around 2 minutes and nothing happens. 
Does anyone else have the same issue or a workaround? Things I have tried:
→ restart the game
→ start the game with admin rights
→ restart my computer
→ change system language
Please help, I am sitting here for two hours now and want to enjoy this wonderful game
