Photoshop taking up hundreds of gigabytes

[Gerardo8]

i have a macbook pro M2 2022 with 8GB RAM and 256GB of storage. The system data only takes up 20GB of the storage, but when i open up photoshop and edit with it, it goes up to 150gb, it says that scratch disk is full and i can't continue my work. I already tried to clean the system data as much as i could but photoshop still took tons of space in my storage. What should i do?

@Gerardo8 how large are the files you're working, can you post a screenshot of the Photoshop interface with the document properties panel opened

 they're not very big files

What is the pixel size? How many documents open? How many history states (each state can potentially add the full size)? Any smart objects?

It all adds up. A scratch file of 150 GB is nothing extraordinary, I've seen much bigger than that.
