I’m not aware of any English-speaking country where it’s pronounced different (maybe certain heavy accents, particularly non-native speakers, pronounce it differently). But it’s the same in both British and American English. A soft u sound.
And it’s a homonym with won, which is pronounced the same.
Soft o and soft u are not terribly far apart so I guess that’s part of it.
And of course like so many English words (since it’s a mutt language) it doesn’t follow many established rules.
What does it sound like to your ears?

I’m English (northern), and “one” rhymes with “on”, not “un”.
Honestly, I’ve never noticed any British accents that pronounce it differently than that, but I guess it’s not Impossible.
I watch a LOT of British TV, have for decades, including Parliament.
You’re smoking crack.
Look, here’s an example - first verse “Earth has one moon”
