Both 5e and the 2024 rules only crit / crit miss on attacks. But Baldur’s Gate 3 introduced them on checks, which muddied the waters.
BG3 also did drinking potions as bonus actions, which 5e did not do but many DM’s (including those in several well-known real play shows) did as a house rule, then they incorporated it into the 2024 rules.
