For those that are past the escape from Abstergo, but haven't gotten this achievement to unlock, there is a fix to try for the Xbox Series S/X platform.
1> Click on the Xbox button
on your controller and scroll down to the Ezio Collection game. Click on the menu button
and then click on "Manage game and add-ons"
2> Click on Compatibility Options
3> Uncheck FPS Boost (this will force close your game)
4> Go back into Ezio Collection/ACII and start a new save file
5> Play for 5 or so minutes until you escape from Abstergo. After you get out of the car trunk and start walking around the new area, the achievement should pop.
Hope this helps some of those stuck on this very early on achievement!
