Clash: Part 1, the title of the 390s, suggests the beginning of a new situation and storyline in the Succession Contest arc. The last manga volume is 36. It only covers up to chapter 380. This means there are ten known chapters that aren''t recovered in physical form.
Viz Media is working on the localization of the manga. Crunchyroll is streaming the anime adaptation. There is no release date for the next chapters of the manga yet.
