Again:

Please see the guide on MDX syntax https://mdxjs.com/docs/what-is-mdx/#jsx
A JSX block can either be inline or block, in your example line 1 is inline, the error is correct for inline content, there is no closing tag on line 1.
You want it to be a block, to do so use:

<p>
a
</p>

Aah, sorry, I was upgrading from an older version of mdx which worked for this example
