Vertically align vertical text in booktabs and multirows

Question

I am trying to create a table such as the one presented here, but the text within the first two columns should be centered vertically. However, I am not able to achieve it. What am I doing wrong? I have a warning of "bad \vbox", which I guess its causing the problem, but I do not know how to solve it.

The MWE:

\documentclass[
    ngerman,
    accentcolor=9c,% Farbe für Hervorhebungen auf Basis der Deklarationen in den
    type=intern,
    marginpar=false
]{tudapub}
\usepackage[english, main=ngerman]{babel}
\usepackage[autostyle]{csquotes}

\usepackage{booktabs}
\usepackage{multirow}
\usepackage{mwe}

\begin{document}
    \begin{table}[!h]
        \centering
        \begin{tabular}{ccccccc}
            \toprule
            &%
            & Central Layer%
            & \multicolumn{4}{c}{Top Layer}%
            \\
            \cmidrule(lr){3-3}
            \cmidrule(lr){4-7}
            &%

            & X = 0 \& Z = -2b%
            & X = ann \& Z = 0%
            \\%
            \midrule

With the help of valign=c from adjustbox, \Block and NiceTabular from nicematrix and \makebox[0pt]:

\documentclass[
