For fans in the USA, the 2022 cyclocross world championship from Fayetteville, Arkansas, will be live streamed by GCN+. GCN+ is a subscription streaming service for computer, smart TV, and mobile devices.
This event will not be on FloBikes. FloBikes previously published a press release announcing a new 4 year deal to carry the UCI world championship in every discipline of cycling. As of this writing, it isn't clear why FloBikes doesn't have streaming rights for this event. I've reached out to them for comment.
Happy streaming!
