Hi itsmemyles
Welcome to the Apple (user-to-user) Community.
Re: "I'm trying to see what is taking up most of the storage on my MacBook"
Seems your MacBook Pro has very little memory / storage space / free in which to operate smoothly.
(Generally, leaving about 50Gb free will allow for smooth operaton.)
Backing up everything on your Mac is always a good step to take, before deleting any files / freeing up space.
Re: "It loads for hours but never loads the items. Please assist in resolving this".
If you haven't already done so, try emptying the trash, and then restart your Mac (Apple menu >Restart). Then log back in & check if that freed up enough space to allow the process underway in your screenshot to complete.
Else: Apple support have articles online that may be helpful:
ie: Articles are for Monterey MacOS 12 (else choose Ventura at the top if you have updated your MacOS)
