}

let _instance = new NextI18Next({
  otherLanguages: ["de", "zh", "ja", "ko","es", 'nl'],
  defaultLanguages: "en",
  defaultNS: [`common${VERSION_COMMON}`],
  ns: [
    `common${VERSION_COMMON}`,

v4.4.2 of what?
next-i18next is at 15.4.0 and i18next is at 24.0.2 and react-i18next is at 15.1.2

Please provide more information and a minimal reproducible example exactly showing your issue... Not just code snippets.

Hi adrai, next-i18next is v4.4.2, other related version message is like: "i18next": "^14.0.1","next": "~7.0.2", "react-i18next": "^11.0.0". Yes, we are using a old version, and when we keep switch language from UI, we could reproduce this issue, not 100%, but we could repro once if we tried several times. I18n is a blocking process for the project, so we will encounter a page hang, and nothing could show up if tReady keeps false not change to true. Please help investigate, thanks.

[adrai]

Sorry, but your versions are way too old.
You need to update them first.

Is there any chance we could resolve this issue without upgrade version? We are a big project, and it may take a while if we want to upgrade our project versions. Could I know why the current version have this issue? I could not see any error message in console for next-i18next, but the log shows up that tReady is false, and never got update to true.

Hard to help without a minimal reproducible example, sorry.
