Something like this?  I think it'd look better with a line break after
the solo section, but this should give you an idea.  Your example had
everything in parallel, instead of a sequential part.

\version "2.21.0"
solo = \relative c'' { c4 c c c }

desc = \relative c'' { b b b b }
treb = \relative c'' { g g g g }
bass = \relative c { e e e e }

\score {
    { % sequential Music that starts with the solo
        \new Staff = "treb" \solo
    
        << % and now a parallel section of three staves.
           % The label marks which one was the solo before.
           \new Staff \desc
           \context Staff = "treb" \treb
           \new Staff { \clef "F" \bass
        >>
    }
  >>
}
