Excessive storage needed to download a game

Recently out of nowhere any time I’ve wanted to download a ps5 game it tells me I can’t install cus I need more space yet when I press view error it says I’ve freed enough space to resume just to say I need more space afterwards. I’ve tried downloading a 20gb game with 50gb free and it still didn’t work until I got at least 60gb free. Any help is appreciated as I’ve got no idea what it could be.
