    Hello again @ashish_walia, I hope you're well today!

    Which plugin are you using for your translations and to make your site multilingual?
    Could you please visit Dashboard => Settings => Permalinks and then hit "save"?
    You don't need to change your permalinks, simply saving them will re-generate them and hopefully your 404 error will be resolved.

    Please advise,

Thank NAME, for their help.
