Error: Command failed: osascript -e tell app "System Events" to count processes whose name is "Simulator" (-1743)

after I run expo start

the web console open successfully, but the iOS simulator can't work as usual

Error installing or running app. Error: Command failed: osascript -e tell app "System Events" to count processes whose name is "Simulator" 28:69: execution error: 未獲授權傳送 Apple Event 給「System Events」。 (-1743)

How can I fix this?

I used this link to help me figure it out: macOS Mojave, Automator “Not authorized to send Apple events to System Events.” 32

I went to

System Preferences > Security & Privacy > Automation > Privacy: and made sure 'System Events' was checked under xcode

There were others suggesting to restart my mac so that may help as well. Good luck!
