[PR #14917](https://github.com/twentyhq/twenty/pull/14917/files#diff-e37dead9533eef25d3a1ac323bb68e93ad2edbb932e972e48f4c756e3c2d5c0f) upgraded twenty-website to Next.js v15, which requires React 19. However, the twenty-ui package (imported by twenty-website) uses React 18.2, causing a React version mismatch error. Solution : Downgrade Next.js from ^15.5.4 to ^14.2.0 to maintain compatibility with React 18.2 used across the monorepo.
