Can't delete a file in the trash

I downloaded a "High Sierra" installer to create a Parallels VM on my MacBook Pro running the latest Monterey.

And now I can't remove the installer file "Install macOS High Sierra" from the trash. I get The operation can't be completed because the item "Install macOS High Sierra is in use".

Here's what I've tried, none of which have worked:

• Right-click, "Delete immediately."
• GetInfo and unlock the panel with my admin password
  • Set permissions on the file to give my account read/write access
  • The "Locked" checkbox is greyed out, but unchecked even with unlocking the panel with my root password
• Terminal mode

$ sudo rm -rf /Users/sparker/.Trash/Install\ macOS\ High\ Sierra.app
Password:
rm: /Users/sparker/.Trash/Install macOS High Sierra.app/Contents/SharedSupport/InstallESD.dmg: Operation not permitted
rm: /Users/sparker/.Trash/Install macOS High Sierra.app/Contents/SharedSupport: Directory not empty
rm: /Users/sparker/.Trash/Install macOS High Sierra.app/Contents: Directory not empty
rm: /Users/sparker/.Trash/Install macOS High Sierra.app: Directory not empty
$ sudo lsof /Users/sparker/.Trash/Install\ macOS\ High\ Sierra.app
$

• Move the file from trash, and try the `sudo rm -rf ...` from the Desktop
• Reboot in safe mode, and try all the things above

Any idea how to get rid of this file? I'm surprised that I can't do it with `sudo`, but I know that apple bastardized the meaning of `sudo` in recent OS releases...
