rescaling xymatrix diagram is not sufficient to resize

Question

Hi I have the begining of the following diagram but it doesn't work

\documentclass{article}
\usepackage{amsmath}
\usepackage{xcolor}
\usepackage[all,cmtip,color]{xy}

\begin{document}

\[
\resizebox{\displaywidth}{!}{%
    \xymatrix{
        \mu_{\Delta_{M_{12}}}(hom(q_{2}F_{1},q_{1}F_{2}))\otimes \mu_{\Delta_{M_{23}}}(hom(q_{2}G_{1},q_{1}G_{2}))\otimes \mu_{\Delta_{M_{34}}}(hom(q_{2}H_{1},q_{1}H_{2})))\ar[d]&\\
        L\circ K (\mu_{\Delta_{M_{12}}\times\Delta_{M_{23}}\times\Delta_{M_{34}}}(F_{1}\otimes G_{1}\otimes H_{1}, F_{2}\otimes G_{2} H_{2}))&L\circ K (\mu_{\Delta_{M_{12}}\times\Delta_{M_{23}}}(F_{1}\otimes G_{1}, F_{2}\otimes G_{2}))\times\mu_{\Delta_{M_{34}}}(hom(q_{2}H_{1},q_{1}H_{2}))
    }%
}
\]

I constantly have a message "dimension too large"?. Someone has an idea on how to fix this ?

\end{document}

UPDATE :

I try to edit with t

\documentclass{article}
    \usepackage{amsmath}
    \usepackage{xcolor}
    \usepackage[all,cmtip,color]{xy}
    \usepackage{tikz-cd}

\begin{document}
\[
\resizebox{\displaywidth}{!}{%
\begin{tikzcd}
\mu_{\Delta_{M_{12}}}(hom(q_{2}F_{1},q_{1}F_{2}))\otimes \mu_{\Delta_{M_{23}}}(hom(q_{2}G_{1},q_{1}G_{2}))\otimes \mu_{\Delta_{M_{34}}}(hom(q_{2}H_{1},q_{1}H_{2})))\arrow[d]&\\
L\circ K (\mu_{\Delta_{M_{12}}\times\Delta_{M_{23}}\times\Delta_{M_{34}}}(F_{1}\otimes G_{1}\otimes H_{1}, F_{2}\otimes G_{2} H_{2}))&L\circ K (\mu_{\Delta_{M_{12}}\times\Delta_{M_{23}}}(F_{1}\otimes G_{1}, F_{2}\otimes G_{2}))\times\mu_{\Delta_{M_{34}}}(hom(q_{2}H_{1},q_{1}H_{2}))
\end{tikzcd}%
}
\]
\end{document}

And now I get an error message Undefined control sequence. } and the diagram is completely collapsing.

This might work, but looks bad. I'd recommend doing a rewrite, for example: "For the same of brevity let $A = \mu_{\Delta_{M_{12}}}(hom(q_{2}F_{1},q_{1}F_{2}))\otimes \mu_{\Delta_{M_{23}}}(hom(q_{2}G_{1},q_{1}G_{2}))\otimes \mu_{\Delta_{M_{34}}}(hom(q_{2}H_{1},q_{1}H_{2})))$ .... (diagram with A, B and C)"
