"How to delete "DataVaults" from Trash?:[...] It is impossible to delete it,: even if I use 'sudo rm' commands in Terminal."

Fixing This:

Install the MacOS Anew, then Migrate:

To delete this, you need to reinstall manually. The file would be deleted. So, you'd backup the Mac, erase the hard drive, Install the macOS anew, and then migrate it back from the backup first mentioned. Is things cannot be transferred, then contact the Developers. I'm no so certain how long a backup would take, but you'd need to back it up prior to the new install, if no recent backup already exists.

Step-by-step:

1. Create: a Time Machine Backup using an external Hard Drive
2. Install: from a USB Installer created for macOS 10.15 Catalina
3. Migrate: items from your TMB
4. Download then Install: the applications, getting the installations back from the Developers.

There is one file that could not be delete. So, I spoke with Apple, did research, and a full, clean reinstall ended up fixing it all. So, it's a 3 page thread, but it you read it, you'll see what I am getting at.
