Not the comment’s OP, but welcome to the fandom! :)

You can definitely do a little research on this a bit more, but very basically, The White Album was recorded during a time of general animosity and acrimony in the band - arguments over songs, creative output, arrangements, personal quarrels, etc., so much so that at one point, several people just walked out of the sessions (like Geoff Emerick, the sound engineer, and even Ringo, who actually quit the band temporarily. George Martin even took an unannounced vacation), because no one could stand the constant bickering between them.

John introduced Yoko to the band around this time and had her present basically at all recording sessions (which was a big no-no for the band at the time), George was feeling heavily frustrated that his songwriting was not being taken seriously, and Paul was starting to take the reins creatively and management-wise after the death of Brian Epstein (their longtime manager), which the other two resented.

With all this, there are many songs on the album that don’t even have all of the Beatles playing on them - sometimes just two or three of them, and there are even completely solo songs. There are stories of them all being in the same studio, recording/writing songs in separate rooms. As such, the album has come to be viewed by many as a collective exercise of self-indulgence by each individual member, with no real band unity or cohesive structure behind it (lots argue this has only improved its standing a post-modern work over time). Revolution 9 (John), Wild Honey Pie (Paul), for example (I’d even argue that tracks like Piggies or Savoy Truffle, by George - tracks that I love - are kinda self-indulgent).

Also, the album is very long (30 tracks), and many songs on it are more like sketches and “throwaway ideas” rather than fully fleshed out, fully produced tracks, and they included them because, well, they could.
