Background
The Chaos Chapter: Freeze marks the beginning of a new series in the TXT's discography, following their Dream Chapter trilogy (2019–20), and their third EP Minisode1: Blue Hour (2020), which served as a "bridge" between the two series and their first Japanese album Still Dreaming released in January 2021.

On April 29, Big Hit Music uploaded a 30-second video trailer to its YouTube channel. The clip showed a pixelated X from TXT's Minisode1 era transforming into a blue cube that shattered to form the X of the TXT logo. At the end, a pink heart emerged in the blue X and the sentence "The Chaos Chapter: FREEZE will be released on May 31 at 6 p.m. KST" appeared on screen, revealing the album's title and release date —preorders opened that same day. Three versions were made available for purchase: "World", "Boy", and "You". On May 2, Big Hit posted a promotion schedule online detailing various events leading up to the album's release. A concept trailer for the new era was released on May 10 via the Hybe Labels official YouTube channel. Concept photos for each of the album's versions were released on May 15, 17, and 19 respectively. The album's eight-song tracklist was publicized on May 24, with "0X1=Lovesong (I Know I Love You)" featuring Korean singer Seori revealed as the lead single. Several songs on the tracklist feature writing credits from various TXT members, as well as a production credit for vocalist Hueningkai on the track "Dear Sputnik". An album preview, featuring a mix of excerpts from all eight songs was released on YouTube the following day.

Release and promotion
The album was released on May 31 as announced. Musically it incorporates various genres such as pop, rock, punk, alternative, and disco. On July 18, Big Hit revealed the release of a repackaged version of the album—TXT's first repackage—titled The Chaos Chapter: Fight or Escape through a 25-second long teaser clip posted to the Hybe Labels YouTube channel. In line with the band's previous releases, the album was made available in "multiple formats" and contains various memorabilia, including a photo book, lyric poster, photo card, sticker pack, and AR card. The preorder period began at physical stores and via online sites on July 19. The album's cover art and 11-song tracklist were revealed on August 6—it included three new songs: the lead single "Loser=Lover", "MOA Diary (Dubaddu Wari Wari)" dedicated to the band's fanbase known as "MOA", and an Emocore remix of "0X1=Lovesong (I Know I Love You)". The album and single, together with an accompanying music video, were simultaneously released on August 17.

Singles
"0X1=Lovesong (I Know I Love You)" was co-written by BTS member RM. Video teasers were released on May 28 and 29 respectively. The single and its accompanying music video were released in conjunction with the album on May 31. Korean singer Seori's vocal feature on the track marked TXT's first collaborative effort with another artist since the band's debut. Seori has said she met TXT on the day they recorded the song and that "their support made [recording] very easy."

"Magic" is TXT's first official English single. It was released on US radio on June 1, 2021, as the second single to be promoted from the album. Written by Olly Murs, the disco-pop track features "the feel-good, classic pop sound" the band is known for, with "breathy falsettos" and "flirtatious lyrics" while the bridge is reminiscent of an S Club 7 song. The band promoted the single with a series of appearances on American talk shows, and presented its premiere performance on ABC's Good Morning America on June 10, additionally participating in an interview to discuss the track. An accompanying "space-age" music video, released on June 11, was preceded by a teaser on June 9 which showed the band "trapped on a spaceship, running away from gunfire." The band subsequently performed the song on CBS's The Late Late Show with James Corden on June 15. A performance video featuring TXT dancing to the song outdoors on a rooftop helipad while dressed in coordinated white shirts and blue jeans was released on June 30.

TXT promoted the repackage through a series of appearances on various domestic television music shows, beginning with their first performance of "Loser=Lover" on Music Bank on August 20. The group won two first-place trophies for the song: on The Show on August 24, and Show Champion on August 25. The album's eighth track, "Frost", was released on October 28.

Critical reception
At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream critics, the album has an average score of 89 based on 4 reviews, indicating "universal acclaim". Writing for Billboard, Heran Mamo said that "the eight-song project highlights the hybrid pop-rock romantic title track "0X1=Lovesong (I Know I Love You)", featuring South Korean singer Seori. The numbers in the title represent how in the midst of chaos where nothing matters, the boy's love interest is his one and only priority." Teen Vogue's Sara Delgado wrote that "On Freeze, TXT traffic in extremes and, as a result, their stronger tracks are stronger than ever before." In her review for Pop Matters, Ana Clara Ribeiro stated that the album "presents a wide range of styles, but there's a streamline tying its songs together. It operates through a new concept of cohesivity, one that embodies variation to some extent". She further commented that it "makes bold statements in unpretentious ways with its production and creative choices", and "fe[lt] like a natural continuation of TXT's path" while "also showcas[ing] new sides of the members' potential as singers, songwriters, and producers". Ribeiro concluded by saying that "you can hardly blame someone for expecting big things from TXT once you hear what they can do in The Chaos Chapter: Freeze" and rated the album 8 out of 10.
