laravel10 upgrade vite revert to laravel-mix problem

I’m upgrading a fairly well advanced project from laravel 9 to laravel 10. Had a few issues but mostly these are resolved.

When I now do tests in the browser it is saying Vite manifest not found I’ve removed vite from npm removed the vite js file and reinstalled laravel-mix via npm. When i run npm run dev it compiles successfully using mix but when I reload the page it says vite manifest not found.

I followed the following tutorials:
https://github.com/laravel/vite-plugin/blob/main/UPGRADE.md#migrating-from-vite-to-laravel-mix (near bottom of page)
https://github.com/laravel/vite-plugin/blob/main/UPGRADE.md#migrating-from-vite-to-laravel-mix

Any ideas? How is my browser thinking I’m using vite? The correct assets are created via mix but this is not used.

thanks
