Switching from block to classic visual and update page corrupts YT embed code

If I have some Youtube video embeds in block editor (using block embeds) then switch to classic editor viewing in visual all is fine.

But if I then update the visual editor at all (even with no edits) then the videos do not show on the page.

If I look in the classic editor text (code) view I see the last few lines of code

<div class="wp-block-embed__wrapper">https://youtu.be/xxxxx</div>
</figure>
<!-- /wp:embed -->

If I just change some line breaks in the last three lines slightly to this:

<div class="wp-block-embed__wrapper">
https://youtu.be/xxxxx
</div></figure>
<!-- /wp:embed -->

And all works fine again.

Could it be the classic visual editor is adding some invisble <p> tags or something that breaks it?something
