This error is because of a conflicting version of TypeScript. Your project requires TypeScript version 5.2.2, but a dependency in your project (class-variance-authority) requires TypeScript version between 4.5.5 and 5.

There are few ways to fix this issue:

  1. Downgrade your TypeScript version to meet the version requirements of the class-variance-authority package. You can do this by running npm uninstall typescript and then npm install [email protected].

  2. Upgrade the class-variance-authority package if a newer version is available which supports TypeScript version 5.2.2. You can do this by running npm update class-variance-authority.

  3. Use the --force or --legacy-peer-deps flags when installing your packages. This will force npm to resolve and install all dependencies regardless of any version conflicts. This could potentially lead to broken dependencies though, so use with caution. Run npm install --force or npm install --legacy-peer-deps to do this.

Remember to backup your project before making any major changes like these to your dependency tree.
