You should be able to get by this error with the following mand:

npm install --legacy-peer-deps

This previous post goes into detail about what --legacy-peer-deps is doing here.

In short, @vitejs/plugin-react (specifically the version 2.2.0 you have as a dev dependency) has listed an older version of vite (vite@"^3.0.0") as one of its peer dependencies, but it is finding the newer vite@"^4.0.4" installed. For reasons that I can't totally explain (see the linked post or Google if you're curious), NPM is not able to resolve this peer dependency conflict as it usually would for the regular dependencies and dev dependencies that we're more familiar with. --legacy-peer-deps gets around this by bypassing peer dependency auto-installation.
