Cloudflare captcha endless loop

I'm having this problem in Edge Stable version 156.0.4314.42, but not in InPrivate tabs. I suspected one of my plugins, but even if I completely disable plugins for the web page I'm trying to load it doesn't work. I have to open an InPrivate window now to visit any page using this type of checkbox captcha from Cloudflare. It just started very recently so I'm guessing it corresponds to an update. 

Your Stable-versus-Dev comparison is useful evidence of a channel-specific difference, but it does not establish the cause of Cloudflare error 600010. Keep Stable available for normal access while testing Dev. Update Dev to its latest available build, restart it, and repeat the same test on the same device and network. Then compare a new Dev profile or an InPrivate window, checking whether extensions have been allowed in InPrivate; that setting means InPrivate is not automatically an extension-free test. Record whether the result changes, without disabling browser security protections or trying to bypass the challenge. Submit feedback from the affected Dev browser through Help and feedback, including both browser versions, the error, timestamp, and reproducible steps. Also notify the site operator if the issue affects their service. I cannot confirm an official Microsoft fix or interpret this Cloudflare-specific error from the information provided.
