About the project’s development stage, Haynes stated:

However, the 2023 writers’ and actors’ strike (SAG-AFTRA strike) interrupted the plans. With the prolonged work stoppage and the difficulty of coordinating the cast’s schedules, the project ended up being reworked. The result was what we now know as USS Callister: Into Infinity — the sixth episode of Black Mirror‘s seventh season.
Despite the changes, the article highlights that the interest in turning Callister into a trilogy still exists, leaving open the possibility of new chapters in the future.
