I thought they eliminated them back in 2023? Their announcement is pretty clear on them:
"Cloudflare will never issue another visual puzzle to anyone, for any reason."

Are you sure it's not fake? For example archive.is sometimes sends me orange-colored CAPTCHAs (with "select all the boxes" style) that are never accepted; but if one looks closer at them, it actually never says "cloudflare" on them anywhere, nor there is a logo (it does this because it has a long-standing feud with cloudflare re users' privacy).
