Encountered Same Issue

[Leo Hui]

maybe you use file protocol because:

Download the React DevTools for a better development experience: https://reactjs.org/link/react-devtoolsYou might need to use a local HTTP server (instead of file://): https://reactjs.org/link/react-devtools-faq

[Alex Kilian]

Any solutions for this? I don't have a manifest.json nor a _meta folder

[James Montalvo]

Per electron/electron#23662 and electron/electron#25198, you need to add allowFileAccess option in newer versions of Electron, e.g.:

installExtension(
	REACT_DEVELOPER_TOOLS,
	{ loadExtensionOptions: { allowFileAccess: true } }
);
