There's just no point buying that because chances are it wont fix anything and if your internal SSD was causing an issue it most likely will start causing more issues after some time. And when your xbox SSD is broken you're out of luck as those can't be replaced by yourself as they are tied to the console. If you're still on warranty you can request service if your console is having an issue.
But like i said if you're out of warranty your best bet is wait for the sales in November-December and get yourself PS5 that will have less issues with the game. If you were on series s this will also be noticeable upgrade. Or at least that what's im gonna do.
