On November 1, 2021, French Montana announced the album alongside its title, cover art, and now-original release date.[1] The album was supposed to be released on November 12, 2021, but was pushed by exactly one week for unknown reasons. The cover art of the project is inspired by the time when he was rushed to the hospital in November 2019 due to heart issues and nausea. Montana wrote, "grateful to be here to tell [his] story" and "2 years ago this same day, [he] was in [the] ICU fighting for [his] life. Loss of memory lost friends lost hope almost lost it all …. and when [he] was down [he] found out all [he] had was Allah… [Allah] picked [him] up and gave [him] a second chance …. while [he] was trying to bounce back they counted [him] out, and forgot everything [he] did". Exactly a week later, he revealed its tracklist.[2] The track "Splash Brothers", which features Canadian rapper Drake, was originally supposed to appear on the album as the original fifth track before the tracklist got updated about a week later. The reason for the removal of the song was upon Drake's request prior to the album's release as he did not want to release or be featured on new music at the time due to the deaths from American rapper and singer Travis Scott's annual weekend Astroworld festival that occurred on November 5, 2021, in which Drake also performed at. However, Montana revealed that he plans to put the song on the upcoming deluxe edition of the album.[3]
The album's lead single, "FMWGAB", was released on June 11, 2021, and a remix that features American rapper Moneybagg Yo also appears on the project.[4] The second single, "I Don't Really Care", was released on October 29, 2021.[5] The third single, "Panicking", a collaboration with American rapper Fivio Foreign, was released on November 5, 2021.[6] The fourth and final single, "Handstand", a collaboration with American rapper and singer Doja Cat that features American rapper Saweetie, was sent to rhythmic contemporary radio on November 23, 2021.[7]
They Got Amnesia received generally favorable reviews from critics upon release.

Ultimately, Murray believed the album "succeeds in its ability to balance punchy, straight-up rap with a tinge of the bittersweet", and gave the album a rating of 7 out of 10.[10]
