Where is the folder containing trash in ventura?

Using FAF I could see that the Trash folder is in:

/Users/your_user_name/.Trash

As reference FAF(Find Any File) can be downloaded here:

https://apps.tempel.org/FindAnyFile/index.php

Am not 100 % certain.

Think the Trash Folder would be not accessible to the User nor any Third Party Application.

Though the Application may tout it can Recovery File Removed from Trash via the Empty Trash Function.

It really doubt that would be possible

Specifically in macOS 11 Big Sur, macOS 12 Monterey and macOS 13 Ventura. 

The Operating System resides in a Sealed and Read Only Volume that can not be opened by the User nor by Third Party Applications.

Monkeying around in such areas of the Operating System could be dangerous to the health of the Computer IMHO

Have you tried restoring from your Time Machine backup? If you don't have a Time Machine backup then I doubt that you will be successful.

Hidden Files and Folder are hidden for a reason.
