I'm not sure this resolves the issue, the vite dev react-router is not for releases. I have also tried to configure the react-router package without any luck.

export default defineConfig({
  optimizeDeps: {
    include: ['react-router-dom'],
  },
  build: {
    commonjsOptions: {
      include: [/react-router/, /node_modules/],
    },
  }
});
