I'm attaching a repro, repro.zip. Download it, install dependencies, and visit /demo. In browser's title bar you should read something like "common:page_title" instead of the label.

export const generateMetadata = async ({ searchParams }: any) => {
  const t = await getT(searchParams.lang, ["common"]);
  return {
    title: t("common:page_title"),
  };
};

Ok, the problem is that we serialized the config in the last release... And after serialize it getT can't access to loadLocaleFrom... So probably we introduced this issue in 2.4.3... Meanwhile, as a workaround you can overwrite the global config:

import config from "../../../i18n";
import getT from "next-translate/getT";

export const generateMetadata = async ({ searchParams }: any) => {
  globalThis.__NEXT_TRANSLATE__ = { lang: searchParams.lang, config };  // temporal workaround
  const t = await getT(searchParams.lang, "common");

  return {
    title: t("common:page_title"),
  };
};

Fixed in next-translate-plugin 2.4.4. Thanks for your contributions reporting these errors @brunoscopelliti
