I accidentally added a incorrectly formatted field in order to track automatic updates on my computer. When I try to run the command:
defaults delete /Library/Preferences/com.apple.SoftwareUpdate "^AutomaticCheckEnabled", it doesn't work.
The error is: Domain (/Library/Preferences/com.apple.SoftwareUpdate) not found. Defaults have not been changed.

Python Entries:
To create:
command = f"sudo defaults write {self.path} {self.key} -int {target}"
To delete:
command = f"defaults delete {self.path} {self.key}"

Output of default read /Library/Preferences/com.apple.SoftwareUpdate:
