\begin{document}
\leavevmode

  Test
\end{minipage}

\hfill
\begin{minipage}[t]{.833\textwidth}

\end{minipage}
\rlap{\thepage}

\end{document}

The number "1" and the text "Test" should be vertically aligned, but with the version 20220807 of luatexja they are mis-aligned.

Sorry, the line 337 of ltj-direction.lua

          if #wh==1 then wh[1]=nil else wh[#wh], wh[1]=nil, wh[#wh] end

is the cause.

There are some solutions:

1. Simply commenting out (or removing) this line:

             -- if #wh==1 then wh[1]=nil else wh[#wh], wh[1]=nil, wh[#wh] end

2. Surrounding this line by if gc~='vtop' then ... end:

             if gc~='vtop' then 
                 if #wh==1 then wh[1]=nil else wh[#wh], wh[1]=nil, wh[#wh] end
             end
