Is Stuart the lead, and who is returning?
Yes. Sussman returns as Stuart, who is identified as the story’s central character. The announced returning cast also includes Lauren Lapkus as Denise, Stuart’s girlfriend; Brian Posehn as Bert, his geologist friend; and John Ross Bowie as Barry Kripke, the quantum physicist who joins their effort.
That core announcement is not a promise that every original cast member will return. A later episode report identifies Kunal Nayyar appearing as Raj, but an episode appearance does not establish him as a regular. The full guest cast and any additional appearances are not established by the cited announcements.

What is Stuart Fails to Save the Universe about?
The disaster begins when Stuart breaks a device built by Sheldon and Leonard. The mistake triggers a multiverse crisis, and Stuart, Denise, Bert, and Barry try to restore reality. Their effort brings them face to face with alternate-universe versions of familiar characters. Warner Bros. Discovery’s synopsis sums up the likely problem with the rescue in its closing line: “As the title implies, things don’t go well.”
The premise gives this spinoff a science-fiction and multiverse framework while retaining comedy. It shifts attention to Stuart and his companions; the original sitcom centered on a group of Pasadena scientists. The announcement does not establish a particular camera format or other production distinction.
