I've seen some bitching about that Tokugawa-Japan-inspired steampunk trilogy he did at the start of his career, but surprisingly little considering he's a white man who dared to write a book from the perspective of a teenage Asian girl.
Most of the biggest names in publishing are basically immune to cancel culture so long as they aren't explicitly "anti-woke" in their public statements like Jo Rowling is, as long as their written work doesn't cross certain thresholds. She is, in fact, the perfect example of this. The Harry Potter books contain many things that you would imagine the stereotype of a woke person to object to:
"Fat shaming": Happens to multiple characters Harry doesn't like. Biggest example being Dudley, who is descdibed in the latter books as "growing in the wrong direction," and this is connected to him being a glutton. Umbridge is also described as being fat, as is Crabbe & Goyle.
Mocking SJW's: Hermione with S.P.E.W. is seen as a parody of white woke girls. Her hunger strike in Goblet of Fire on behalf of the house elves is mocked by every other character. The minority she is advocating actually enjoys their condition and don't want to be freed.
Women with "male" physical features tend to be villains: See Rita Skeeter, Petunia, Marge, Umbridge, etc. And Pansy, while not described as manly, is not feminine either, described as ugly, shrill, and pugfaced.

And yet, and yet...
Most SJW's LOVED Harry Potter and would defend it from the view SJW's who had complaints. Frankly, it was the right who were trying to cancel Harry Potter back in the day, due to witchcraft and much later due to Rowling opposing BREXIT & Trump. On 4CHAN, being called a Potterhead was one of the worst things you could be called.
It was not until Rowling became outspoken against the trans folks that the left turned on her. Nowadays, people who never cared about how house elves were depicted in the Harry Potter adventures are complaining about it.
If Kristoff starts praising Trump, well, then he'll be canceled for that & for cultural appropriation. But otherwise, he's safe.
The truth that some of you might not realize is that nine out of ten SJW's are perfectly fine with certain cultural appropriation tropes and many other "microaggresions" that you think they wouldn't be fine with. Number ten will whine & complain & get mocked on Twitter, but they won't get reinforcements from the nine unless something big changes in the books or areal life threshold is crossed.
P.S. And even after all that, J.K. Rowling still is too big to cancel. And to add more emphasis to that, there are still to this day, woke Harry Potter fans (only now, it's one of ten rather than the whole nine of ten) who hate Rowling but who still like her world.
