PS5 Loading while still playing

on the PS5 you can get the loading screen to show up as you are playing fairly easily.
If you go into your inventory so often you can get it so the game needs time to load if you go out of the inventory that loading screen will stay on screen and you'll be able to play with a red background and the grinding gears loading. the only thing you can see it anything you can click on(ie; pots, chests, checkpoints)
