i just faced the same warning when i upgraded from vite 5 to vite 8.
just remove the @vitejs/plugin-react-swc or @vitejs/plugin-react-oxc plugin if present and install @vitejs/plugin-react

npm install --save-dev @vitejs/plugin-react

then in your vite.config.js or vite.config.ts change this line:

import react from '@vitejs/plugin-react-swc'; // or `@vitejs/plugin-react-ocx`

to

import react from '@vitejs/plugin-react';
