Cannot set up as sole trader in tax account

Dear sir/madam, I am writing to enquire about how I can set up as a sole trader in my self assessment. I have a personal tax account and have submitted my self assessment for the 22/23 tax year. Only in the 23/24 tax year I started working as a sole trader, so I wanted to add that into my tax account. I clicked the "business tax" tab and navigated to https://www.tax.service.gov.uk/business-account. However, I couldn't find the option for "sole trader" from the list of tax I can add, and hence selected the "other taxes of schemes" option. Then I was instructed to set up a new organisational tax account for adding the tax I was looking for. After setting up a new organisation tax account, I finally found "sole trader" from the list of tax I could add to the account. However, after entering my UTR in the organisation tax account, I was told that "You already manage your taxes, duties and schemes online" and had to re-sign in with my personal tax account; I followed the instruction and re-signed in with the account I already had and had submitted self assessment for the 22/23 tax year, yet finding myself never able to add any tax as a sole trader in my personal tax account! This loop perplexes me. Please advise how I can set up myself as a sole trader online - how can I do it with my personal tax account, as setting up an organisational tax account provided no help but mandating me to re-sign in my personal tax account? Thank you.

I got the same problem - though your response did not solve the issue. Would you please advise how I can register a sole trader, given I already have UTR and Self Assessment account due to my previous full-employee job? Thanks,
