I think you should opt-out of sandbox mode in the xcode project.

Something like that in your Profile.entitlements:

<key>com.apple.security.app-sandbox</key>
<false/>

I triggered the pusheter initialization through a button, and the above error disappeared, but error changed to

com.apple.security.app-sandbox

I had modified the plist file in macos.

var browser = await puppeteer.launch(
devTools: false,
executablePath: BrowserPath.chrome,
noSandboxFlag: true,
args: puppeteer.defaultArgs(),
headless: false,
userDataDir: "profile-folder"
);
this is my code
