How do a stop lag?

I know sounds like a dumb question it kind of is but I have a reason sadly this is because It's only one game that is affected and it doesn't matter what I do to fix it I don't want to delete the game and all of it's saved data and I don't think that will guarantee anything.

Ok so I like many other people have Minecraft on my series X and and right from the start. I mean opening the game the loading screen, the menu, In game play both online and offline does this occasional shuttering thing every 1 to 5 minutes where the game stops and loads sometimes with a little bit of rubber banding.

I have tried common solutions to fix it.

- Restarting console

- Unplugging console/reset cache

- Uninstalling/Reinstalling games

- Disconnecting/Reconnecting internet.

I understand minecraft is a graphics intensive game but this is a Xbox series X I saw it would be able to handle the games home screen. I don't know what to do now.
