How to fix when Mac Studio internal drive storage is full

This is a mac studio running Ventura 13.6.3, M1 max chip, and 2TB internal SSD. This has been an ongoing problem for months now, and has not changed with system updates. I do video editing so I go through a lot of very large files. Today I deleted all the files from a previous project, about 1.3 TB of data. I emptied the bin, and there was no change in my mac HD available space. I went to setting-general-storage and it still showed documents taking up most of the drive. While sitting there scratching my head, the documents file dropped in size only to be replaced by system data of the same size. It's moving the deleted files into system data for some reason and still occupying my drive space. If I reboot or wait a couple hours it will usually work itself out, but that's not exactly convenient for my work flow. How can I get this thing to let me delete the files immediately?

I should mention that I've tried relaunching finder and doing a first aid on the drive. No help there. Also, today even after rebooting there is still no room. There's a huge system data file that I can't do anything about.
