@yasserak , assuming that you are US person ( citizen / GreenCard ) and therefore filed a form 5471 during 2020 tax year denoting that this was the final 5471 --- did you check that box ? ---- there is no need for another 5471, since in 2021 you had no official role in that foreign entity.
For FBAR, if the account earlier reported no longer exists, then there is nothing to report. If you have other foreign accounts , then those need to show up on 2021 FBAR and also noted ( check box ) on your 2021 return.
Does this help ?
