Game cannot launch after modifying Xbox settings

I was trying to change my settings regarding multiplayer, as the app told me that I was not able to play in a realm because of my Microsoft account settings. After I have applied changes in on the Microsoft Xbox website, I cannot launch my game anymore, the game would quit in the loading screen, I have tried to reopen the app multiple times, but the game would still quit in the same loading screen. I had downloaded the Xbox app from App Store prior to changing my settings on Xbox website, as pressing the "modifying account" in my in-game profile would redirect me to downloading the app, and I was again redirected to the Xbox website as the Xbox app told me I could use only change certain multiplayer settings on the Xbox website. I cannot launch the game from this point on. The game would be stuck in the screenshot below and quit itself.
