BigSur emptying trash doesn't free up space

[Jinx2406]

hello everyone, right now I have a trouble with free space on mac (bigsur), after emptying trash the free disk space doesn't change, so I have deleted about 100 gigs of files but it still remains as 25 gb of freed space (checked it through disk utility). I use time machine but currently there are no snapshots on ssd, so the crux of the problem is somewhere else. Tried to restart in safe mode but nothing changed. After 4 hours of finding the source of the problem started a tm backup, will see what I get. Anyway, does anybody know how to deal with this bug and what else can be done?
Found this method on the internet but not sure about it, what do you all think?

Have you checked if your Mac is doing internal Time Machine back-ups?

I run Onyx to purge the snapshots and other debris to find out how much space I have left on my m1 Mini's SSD.

Snapshots are not debris, they serve a function.
TimeMachine will eventually purge them after backup.

Agree, TM snapshots on the internal are the likely explanation. More in this post:

Note second sentence of 3, about deleting snapshots manually. If I have just done a big deletion, as the OP has, and Finder is not showing the space I sometimes accelerate the snapshot deletion using Disk Utility.

Snapshots only take up as much space as the differences in the files. So what can look like a huge amount of space used really isn’t. It’s a feature of APFS. That might also be why the OP isn’t reclaiming space if the deleted files were duplicates on the same partition.

Typically when I empty the trash and delete tens-hundreds of GBs of files, a Time Machine backup clears the snapshots that were "keeping" those old files, when my internal SSD's available storage does not change.
