Reproduction

Describe the bug

With ssr: false, the useRuntimeConfig() breaks somehow. I get an error and the entire application is not rendered.

Additional context

It has to do with these lines:

const runtimeConfig = process.server ? options.ssrContext.runtimeConfig : reactive(nuxtApp.payload.config);
  const compatibilityConfig = new Proxy(runtimeConfig, {
    get(target, prop) {
      if (prop in target) {
        return target[prop];
      }
      if (process.dev && prop in target.public) {
        console.warn(`[nuxt] [runtimeConfig] You are trying to access a public runtime config value (\`${prop}\`) directly from the top level. This currently works (for backward compatibility with Nuxt 2) but this compatibility layer will be removed in v3.5. Instead, you can update \`config['${prop}']\` to \`config.public['${prop}']\`.`);
      }
      return target.public[prop];
    },
    set(target, prop, value) {
      if (process.server || prop === "public" || prop === "app") {
        return false;
      }
      target[prop] = value;
      target.public[prop] = value;
      return true;
    }
  });

Logs

Error while mounting app: TypeError: `target` argument of Proxy must be an object, got undefined

This should be resolved in the edge channel via #20216, or in the next release.

Let me know if not and I'll reopen.
