Where's my storage?

I've been emptying my phone because it was pretty full. I noticed that even after removing a ton of files it was still nearly half full (121GB). So I did a storage analysis and found about 76GB 'missing'.

My trash can is empty and I find it hard to believe the few apps I have take up 76GB of space (currently says 0 there).

Any suggestions?

Phone: ASUS zenfone 8

Storage: 256GB

Android: 13

I already rebooted, checked for hidden files/folders, did a virus scan and came up with nothing.
