Using next/dynamic with suspense option set to true under blocking rendering mode will lead to this error.
Concurrent rendering mode is required to be enabled here with using suspense option.
Make sure using React v18 and set reactRoot, concurrentFeatures to true in next.config.js to enable concurrent rendering mode.
// next.config.js
module.exports = {
experimental: {
reactRoot: true,
concurrentFeatures: true,
},
}
