If I download and manually add https://raw.githubusercontent.com/klutchell/dnscrypt-proxy/main/dnscrypt-proxy.toml then the issue is resolved. But for some reason if the folder is mounted the container fails to start

This container won't install a config file for you if you mount a configuration directory, you are expected to provide your own file in that case. The default configuration is only used when a volume isn't mounted, so your process of manually downloading and mounting the config file is correct!
