So, this happens when you have several Vite versions installed. Check your lockfile and resolve the inconsistency. You can also bypass this by using defineConfig from vitest/config. Closing issue since this is not Vitest problem.

Exact same problem here:

yarn list v1.22.19
├─ @vitejs/plugin-vue@3.1.0
├─ @vitest/coverage-c8@0.23.1
├─ vite-plugin-checker@0.5.1
├─ vite-tsconfig-paths@3.5.0
├─ vite@3.1.0
└─ vitest@0.23.1
   └─ vite@3.0.0

One of our devs was so smart to cast the defineConfig({} as Parameters<typeof defineConfig>[0])
