Instagram Account Gone in an Instant

My Instagram account was suddenly terminated without any warning on 07/07/2023, and there were no indications of any problems in the account's history. I attempted to appeal the decision by submitting a form, but my efforts were unsuccessful. After that, I was terminated from the account, and it was removed from the system altogether. For many years, I have been logging in with the same account; however, I am unable to access it at this time. It's driving me absolutely bonkers trying to figure out a solution. Even when I try to find my account by entering my username, it tells me that there is "No account found." I beg the administrators of Instagram to hear this request and help me retrieve my account as soon as possible.
