Hi @Blooon, I tried your tsconfig.json on a fresh Vite + Vitest project and still did not see the same issue.
Could you try the solution shared here? PrismicProvider - Cannot use import statement outside a module - #6 by angeloashmore
Those instructions essentially turn @prismicio/react into an ESM-first package, which could resolve the issue. It would be a temporary fix until we update @prismicio/react.
