The answer is "Robert Jordan was a boomer who probably was never presented with the existence of trans people before he got too far into the series to figure out how to make his gender binary a spectrum," but they do explain that which half of magic you get access to is basically a boolean flag on your soul so presumably a trans channeler would just be someone who's soul got reincarnated into a body opposite whatever that flag was.
kinda sorta spoilers for a minor plot point
There's actually a quasi trans character, though I'm using that term very loosely here, who is a channeler. They were a heavily misogynistic man, pissed off Not Satan quite a lot by failing at something, and got their soul forcibly shoved into a woman's body as punishment. They continued to wield the male half of the Source.
Frank Herbert decreed that men, by essentialist nature, could only be Mentats, and feeemales could (only) be Bene Gessarits, and if a male Mentat eventually got Bene Gessarit powers, his male awesomeness would rule the universe.
Still loved the novels, but that's fucked up ideology.
They go mad because prior to the books the world was a magical scientific utopia but they discovered a source of energy that, if tapped, could theoretically allow people to do basically anything with magic along with eliminating the differences between male and female channelers (since each can only touch half the source of magic, and each half lets them do different things more easily).
Well it turns out this energy source was Not Satan, detected through a thinning in the skin of reality, which they bored through and consequently released
This led to the downfall of the utopia as Not Satan spread his influence and turned people violent and greedy, etc.
Lews Therin Telamon, The Dragon, and his 100 Companions attacked the Bore and used their magic to seal it shut. However, the contact made in doing so allowed Not Satan to connect to Saidin, the male half of the Source, and taint it with malignancy.
It's described as an oily taint on top of a pool of water, you can't dip into the pool without being exposed to the taint, and repeated exposure is essentially guaranteed to drive a channeler insane over time.
980(? i don't know exactly, a long time ago) years ago in the past from the books (what you're referencing in your comment):
spoiler
this guy lews therin was hella powerful with the male magic. him and a bunch other fought the devil and sealed the devil away. the devil, as a last gesture before being sealed away, tainted the male power so anyone who wielded it would go mad.
all the male magic users went absolutely crazy, killed everyone, moved mountains, oceans, etc. literally "broke the world"
the books are generally about the present day and lews therin being "reborn" (debately if true or not) and fighting the devil once and for all

She's not the only one.
I'm a huge fan of the Dune series, but Frank Herbert had some very gross gender essentialist ideology in the foundations of the story.
