offset this years expenses to last year tax year

Hi. I am filing my current self assessment from 6apr22 to 5apr23. I will pay tax for this period. For the period 6apr23 to 5apr24 I know I will pay no tax. I will not have made a loss but my expenses will not used to offset any tax. I have done some further education in this period that will benefit my business and this cost me money. Can I offset this cost onto 6apr22 to 5apr23? thanks!
