It seems that I cannot reference tables when they are placed inside onlyenv, but . This applies to both of cref and the traditional ref

The topic Table numbers in beamer is not an answer to this question because my question is asking about referencing a table, not inserting its number in a caption.

Here is the MWE. When you try to run it, you must do so twice to get the real result.

documentclass[aspectratio=169, xcolor={x11names}]{beamer}





usecolortheme{seahorse}

useoutertheme{miniframes}

useinnertheme{inmargin}

usefonttheme[onlylarge]{structurebold}

setbeamertemplate{caption}[numbered]

newcommand{framePageWide}{

    defGm@lmargin{5mm}%

    defGm@rmargin{5mm}%

    hsizetextwidth

    columnwidthtextwidth

    setlength{linewidth}{textwidth}

    hoffset=dimexpr-beamer@leftsidebar+Gm@lmargin-0mmrelax

}

makeatother

newcommand{framePageWideEnumI}{setlength{leftmargini}{10mm}}

        hfill

        begin{adjustbox}{minipage={0.43textwidth}, valign=t}



            From cref{table:results2} we see that



            begin{itemize}

                item Our method is fast

                item By contrast, Brown's becomes very slow when the system is large

            end{itemize}



        end{adjustbox}



    end{table}



end{onlyenv}
