org-defblock not working

Hello there, and thanks for keeping up your work on `org-special-block-extras`! I have not been using it for a while since I wasn’t preparing presentations using `org-beamer`, but now I am at it again. Unfortunately, though, the macro `org-defblock` does not seem to work for me on the current version (20230721.43). Here is an example definition I use, but I found the problem with any definition:

(org-defblock satz nil (name "" label "" align "" width 0.15)
"Custom block for the custom satz-environment in LaTeX."
(let ((changed-name name)
(align-one (cond
((equal align 'center) "\\begin{center}\n")
((equal align 'right) "\\begin{flushright}\n")
(t "")))
(align-two (cond
((equal align'center) "\n\\end{center}")
((equal align 'right) "\n\\end{flushright}")
(t "")))
(width-two (- 1 width)))
(cond
((memq backend '(latex beamer))

(format "%s\\begin{equation}
\\label{%s}
\\tag{%s}
\\text{\\parbox{%s\\textwidth}{%s}}
\\end{equation}%s \\noindent"
align-one label changed-name width-two contents align-two))

(backend (format "\n\n (%s) \t%s\n" changed-name contents)))))

When using such a block, as for example

```
#+BEGIN_SATZ :name myname :label mylabel
Example Sentence.
#+END_SATZ
```

I get the error message `Symbol's function definition is void: name`.

I had an old version (20220326.1432) flying around so I tried it with that version and everything worked the way I intended it to work. Thus, I suppose that you made some change to some file which blows up `org-defblock`. Would you be willing to look into this, please?
