Available storage is 5GB no matter what I do
Big Sur version 11/6/5
MacBook Pro (12 inch 2019)

I only have 5GB of available storage. But when I restart in recovery mode and check disk utilit it says I have 37GB~ of space.
After I reboot, the second I start using my computer (Photoshop mainly) the available space slowly ticks down until its back to around 5GB. The error seems to come from the other volumes section being inconsistent. Nothing I do seems to lower the disk space anyways—I regularly clean out caches and logs and yet my storage goes up every day even when I don't download things. I attached pictures of the process, this has been happening every couple hours.
I am sure the storage display is inaccurate because there have been times where I have deleted lots of files at once (1GB of photos for example) and available space goes down instead of up. The space shown in recovery mode seems much more accurate.
How do I fix this issue of incorrect storage?
(Also, it's not time machine snapshots as I don't have any backups.)
