Be aware that this disables Gatekeeper, which is intended to protect your system from malware. Disabling it isn't fixing the problem, it's just bypassing it, and leaves your machine vulnerable (although the risks are currently low you should be aware what you're doing).
Did you reboot the system and try again ? It should be solved aftwr terminal command.
I am having the same problem in High Sierra, and cannot open any apps including Terminal...I tried to do a reinstall of the OS and it hangs and never runs, also corrupted. How can I fix this?
App is damaged and can’t be opened inSierra!
