CGT on crypto, mixed residence

Hello Last year I was residing in the UK for two months (between a change in employers) and during this time I liquidated some cryptocurrency and paid off one of my student loans. I received an email suggesting I may need to complete a self assessment for this. I did not pay income tax in the UK in 2023-24 as I was working abroad, but do I need to pay capital gains tax on the cryptocurrency sale as this was made on a UK based platform whilst I was residing in the UK? Note - I've read up a little on this but I'm quite confused. I still have ties to the UK, I have a UK address, bank account etc. and intend to resume full time residence within the next 5 years. Does this make me liable to pay the tax by Jan 31st? Thanks!
