I'm developing an electron app using electron-builder I code-signed and notarized it and can confirm with codesign and spctl commands like below: % codesign --verify --deep --verbose ./MyApp.app ./MyApp.app: valid on disk ./MyApp.app: satisfies its Designated Requirement % spctl -a -vvv -t install ./MyApp.app ./MyApp.app: accepted source=Notarized Developer ID origin=Developer ID Application: XXXXX.,Ltd. (XXXX) But I cannot open it as if weren't signed. "MyApp" can't be openend" If I try to open it in terminal with open command: The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10810 "kLSUnknownErr: Unexpected internal error" UserInfo={_LSFunction=_LSLaunchWithRunningboard, _LSLine=2735, NSUnderlyingError=0x600003aa0900 {Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x600003aa09c0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}}} What could be wrong here? I'm strongly suspecting that my apple developer program and certificate has some issues. As this happened after I renew my program this month. Or could there be some other reason for this error?
