Seems when trying to select any of the magic initiate feats while playing using a controller of any type the UI crashes. doesn't matter which feat it is (cleric, wizard or warlock) and doesn't make a difference between Chromecast or PC but the interface when using a controller is a little broken and when you select the spells to fill the slots it crashes the game. When I switched to the keyboard and mouse UI it worked w/o issue (on PC obviously). I'm playing on Stadia if you didn't catch that from the chromecast reference.
