Can't boot anymore

So the "Microsoft Gaming Service", whatever the hell that is, had an update that appears to have killed my ability to boot up the Launcher. Everything was fine before I saw that prompt, now a process doesn't start no matter where I try to boot from; desktop, start menu, storefront, nothing works.

If PC: Unstall the MS Store version, go to Arks-Layer, install the Tweaker Version (at least until the Steam Launch), install, run the 'fixes', run the MS Store Fix, enjoy the game.

Believe me, it is worth the time.
