How to delete locked app on MacOS (Catalina)

I'm trying to delete a locked app on Catalina. In recovery mode, I disabled SIP, restarted and gave Terminal Full Disk Access.

Tried this:

/Volumes/Macintosh\ HD/Applications/Crashplan.app: Operation not permitted

And this:

xxxxxxxxxxxxxx:~ xxxxxxxxxx$ cd /Volumes/Macintosh\ HD/Applications/
xxxxxxxxxxxxxx:Applications xxxxxxxxxx$ rm Crashplan.app
rm: Crashplan.app: is a directory`

How do I resolve this problem?

You should always first check if there's an uninstaller.
This is dependant usually on whether you just copied the App directly from a .dmg or you ran an actual install .pkg

Uninstaller is in /Library/Application Support/CrashPlan/Uninstall.app or ~/Library/Application Support/CrashPlan/Uninstall.app depending on who it was installed for.
