The most likely possibility is that "Star Wars: A New Beginning" is a working title. While it fits, Lucasfilm would probably want something a bit punchier to kick off a new storyline with Rey at the center. Besides, a previous title has already been shot down. Some outlets reported that the Rey film would be called "Star Wars: New Jedi Order." However, io9 received word from Lucasfilm that the movie would not be called that. The same could very well hold true for "Star Wars: A New Beginning," but we'll just have to wait to see what transpires.
The only thing we do know at this point is that the film will focus on Rey attempting to rebuild the Jedi Order, with Steven Knight set as the current screenwriter, and Sharmeen Obaid-Chinoy attached to direct. As for everything else Star Wars Meg mentions, it's vital to remain skeptical. Even if some of the details are true, there's always a chance something could change. For example, the YouTuber mentions how production on "Star Wars: A New Beginning" will start in April 2024. With the Screen Actors Guild strike still going on, it's possible it could need to be pushed back if the strike continues for a while.
