ContentLayer with MDX doesn't work. "useMemo" problem

[RajinCoding2007]

I was following contentlayer documentation, I got this error:

error - node_modules\next\dist\compiled\react\cjs\react.shared-subset.development.js (1760:20) @ useMemo
error - TypeError: Cannot read properties of null (reading 'useMemo')
