I found a link to her crowd funder on twitter. Won't link obviously. The details given about the events are below. Sounds like the coversations were more specifically about trans women using women's spaces, and there's a bit more about the investigation.
"The chain of events that has led to this began with a party in my own home four months ago with dancers during rehearsals for the company’s production of Romeo + Juliet. Debate turned heated as we talked about the differences between sex and gender and whether transwomen should be admitted to women’s spaces such as refugees for victims of domestic violence. I believe in sex-based protections and women’s sex-based rights. Women’s rights and freedom of expression are a cornerstone to my artistic expression. A complaint to the Board by one of the dancers at the party – a young political activist – led to a four-month investigation by my board which it has botched, first exonerating me, then, when that led to more complaints, opening a second investigation which still hasn’t concluded. I cannot endure this humiliation any longer."
The weird thing from the article was that they were planning a tribunal led by an hr firm? Sounds weird.
She wants to rebuild her career
"After a bit of a break and recovery time, I plan to continue my research and make a new dance adaptation of Virginia Woolf’s novel Orlando. I will also continue to work on my autobiography, which became my most recent solo show Adult Human Female, and I will continue with performing solo works while I build a new company. My new company will be totally artist-focussed, with a lighter structure that lets me, as the creator, stay in control."
(I actually wonder if adult female human is a typo as she had a recent show called adult female dancer)

It's not very clear what the fundraiser is for other than 'legal fees'. Is she suing them, or is it just legal fees in extracting herself from the charity and setting up a new company or whatever.
