Considering 90% of human civilization existed before the advent of gunpowder, what would it take for human society today to still remain technologically as it was centuries ago? What would be the latest POD for such a situation to be possible?

... in other words: design a world where there is no real need for chemistry and metalurgy... frankly a world where there is no need for progress at all.
Airborne syphilis that gets transmitted to the Old World while smallpox and influenza ravage the New World. 95% of people die worldwide in rolling plagues and the ensuing famines. More centralized states survive as a skeleton, while more decentralized ones collapse into city states. After a century or two immunities build up, but the nascent trade networks of the pre apocalypse era are destroyed.
Just have the mongols empire not form
So airborne is probably out. But I maintain a super plague hitting the Old World like smallpox did the New World would be the best bet. Perhaps syphilis transmitted via livestock or food prep, or another disease I'm not thinking of.
The spread of fire or copper or any number of things that took thousand of years is a margin of error slower.
In more recent history I think you need more natural disasters and more collapses like the bronze age one
Well, technically, a postponed neolithic/calcolithic isn't unthinkable.You'd need first to prevent gunpowder being discovered in 9th century China, then you'd need to engineer a world in which people aren't interested in alchemy anymore on a global scale, and even then it'd all be down to luck. Gunpowder was discovered by chance, it can still be discovered by chance. Practically impossible.
