DNS issues for render custom domain

I wanted to make a custom domain to use on render.com and here are my DNS settings I have set up. I have an issue on render which shows that the custom domain is verified but has its certificate pending. I have contacted render about this issue but they responded to me by saying that its odd that "neither the apex or the www are resolving" and that I would have to "contact Cloudflare to understand what the problem here as it's a DNS issue which is outside of Render". Any help with this would be much much appreciated.
