I think we're miscommunicating.  I didn't ask
to see your patch (diff).

I said that if you post here code I can use
to replace the :enable code I showed then I'll
be glad to help out by trying it and letting
you know what I see.  If you don't want to do
that, fine.

And thanks for patching, assuming the result
takes care of the problem discussed.  In that
case, when Emacs releases again (27.2?), with
the patch applied, Emacs will no longer present
the reported regression - the same :enable
will work for all Emacs releases (except 27.1).

In that case, the :enable condition will become:

(or (version= "27.1" emacs-version) ; bug #43569
    (not (condition-case nil
             (tags-loop-eval tags-loop-scan)
           (error t))))

so that the menu item is still enabled
unconditionally for the (presumably still)
broken 27.1.
