lowkey the whole function signature. it takes one thing and returns an int, no cap. 💅

🦋 DESCRIPTION 🦋

Stop the UVD block, mark ring as not ready any more. ✨

that's the whole thing fr fr. it stops the UVD block and then it's like "the ring? not ready anymore, bestie" and flips that status. the ring does not get to be ready after this call. it's giving closing time at the function. 🔥
