o, in me experience, it’s less unhygienic, an' more a problem with not coverin' to the sky their natural smells. Sounds similar, different things. I’ll explain me experience with ttrpgers.

all the ones I know who fall into the funk trap be autistic folk, an' the issue isn’t that there they don’t bathe, it’s that there they can’t stand them strong chemical smells they associate with body washes an' deodorant*. So they bathe, but they use mild soaps, soaps designed fer children, or unscented soaps, an' they don’t wearrr deodorant.

which creates a situation where the 'ygiene be okay, but the funk be still there, once they’re all in a crew together. One on one, ye really don’t notice, but get 10 folks in a room fer game night, or a couple thousand together fer an event or convention, an' the funk becomes overpowerin'.

that there said, I do know two that there 'ave just a general aversion to bathing, an' consistently reek

*edit to add

also an issue with texture on the skin. One o' me best mates be autistic, an' 'e cannot 'andle the feelin' o' deodorant on 'is armpits. It tacks the 'air down, it’s apparently sticky feeling, an' 'e just goes into total meltdown until 'e can get it off. 'e can’t focus on anythin' else.
