The studio just shuffled their 2023 and 2024 release calendar, and among the moves they made, they pushed back their film version of Spider-Man ally Madame Web.
At the same time, a second as-yet-unannounced Sony/Marvel movie that been planned for October 6, 2023 got bumped back to October 6, 2023.
The movie was scheduled to open exclusively in theaters on July 7, 2023.
And of course Venom is a very famous Marvel character; Morbius — and Madame Web — are not.
