1.1.1.1 DNS Broken, Help

I’ve recently tried to update 1.1.1.1 VPN for my laptop, but the terrible wifi may have done something during the update process. I’m on good wifi, but it says DNS not found. This is not an issue of my wifi. I’ve tried searching for Cloudflare 1.1.1.1 in my software lists to uninstall it, but it is nowhere to be found. How do I fix this DNS issue?
