[Xbox][Roblox] please I’ve been searching for years

[ROBLOX][~2017] Game where you start sitting at a desk in front of an old computer, click an app to start the game, then you spawn in a city (skyscrapers, a park, a multi-story parking garage) and you play as a purple ball. Played around 2016–2018. The lobby is a room with a desk/CRT-style monitor that launches different “apps”/modes. The main playable area is a city with a park and parking garage — you control a glossy/purple ball (not your avatar). Any leads appreciated!
