mac application storage taking up more than it does

when i check the storage on my mac (macintosh hd), it says my applications and icloud take up over 250gbs each. i added the total size of all my applications combined and it comes nowhere near 250gbs, with my largest app size being 3gbs.

i've reset my mac, cleared a bunch of storage, deleted most apps, and download third parties to get rid of unneeded files but nothing seems to work. i've tried updating my mac, but it doesn't work because i don't have enough storage to do so.

also my total icloud only uses 150gbs so idek why is says 250😭
