ELectron React Boilerplate random error at start

Question

I have a project, very simple, based on ERB, but 50% of the time I started I get the following error in the (webkit) console:

Uncaught TypeError: Cannot read properties of undefined (reading 'forEach')
    at Object.injectIntoGlobalHook (react-refresh-runtime.development.js:449:1)
    at Object../node_modules/@pmmmwh/react-refresh-webpack-plugin/client/ReactRefreshEntry.js (ReactRefreshEntry.js:17:1)
    at Object.options.factory (react refresh:6:1)
    at __webpack_require__ (bootstrap:24:1)
    at startup:4:1
    at startup:10:1
    at webpackUniversalModuleDefinition (universalModuleDefinition:7:1)
    at universalModuleDefinition:10:2

The application starts, load a blank screen with the above error in the console.

In the terminal I see the following messages:

08:21:21.774 > Skip checkForUpdatesAndNotify because application is not packed
<i> [webpack-dev-middleware] wait until bundle finished: /index.html
[19072:0519/082130.210:ERROR:CONSOLE(160)] "Electron sandbox_bundle.js script failed to run", source: node:electron/js2c/sandbox_bundle (160)
[19072:0519/082130.210:ERROR:CONSOLE(160)] "TypeError: object null is not iterable (cannot read property Symbol(Symbol.iterator))", source: node:electron/js2c/sandbox_bundle (160)

The crazy thing is that yesterday before closing the PC it was working fine, this morning, I've run it again without making any change, the same code as yesterday, and I get the error.

Please give me some hint because I really don't know what to search for!
