Why does Shakespeare want to give up the theatre in ch.11 of cue for treason?

In Chapter 11 of "Cue for Treason," Shakespeare decides to give up the theater because he is disillusioned by the recent events that have caused unrest and chaos in the country. He is also tired of dealing with the political pressure and censorship that come with staging plays during that time. Shakespeare wants to focus on writing his plays without being constrained by the political environment.
