Self Assessment

I came to take on a job in Aug 2023 and left UK in Apr 2024. So 2023-24 is my first tax year (and possibly last). I understand I have to open an account for Self Assessment (remittance basis as well as additional tax relief due to pension contribution). I did it three times. For the first time, I swiftly received a rejection email due to address mismatch (because I used my foreign address when applying when on HMRC record it was still my previous UK address). I amended the address on HMRC and re-apply in late April. There was not any news and I re-applied again in late May. It is June now but I am still receiving nothing and am not sure how I could file my self assessment. Could you shed some light on this please? Many thanks
