I had the same issue, try removing <React.StrictMode></React.StrictMode> from your index.js file

Do you know how to fix it without removing strict mode?

[TrevorDecker]

For me this only shows up for me when I run with nextjs in development mode and only started showing up when I upgraded to react 18. A down grade to react 17 or removal of strict mode from next.config.js and index.js fixed the issue for me

@Mateusz-Podemski-Forte-Digital did you figure it out ? I have the same problem and i'm looking for a way to fix it without disabling strict mode

[Mateusz-Podemski-Forte-Digital]

Unfortunately no, for local development I had to disable strict mode :/

I fixed this issue by using the old ReactDOM.render(...) instead of ReactDOM.createRoot(...).render(...)
