An invalid form control with name=” is not focusable

Hello,

On several sites, I can’t publish articles with Classic Editor. Articles can be deleted, but not published or updated.
I’ve tried on Gutenberg, and it works.
Checking in the Console of my element inspector, here is the error code that arrives when I click on the “Publish” button:

The strange thing is that Classic Editor works fine on my other sites…

Thank you in advance for your feedback
