Student Finance repayment for EU Students

Hello everyone,

I started studies in the UK in 2014 and I graduated in 2019. After finishing my studies I left England and moved back to my country (EU). I kept receiving emails and letters about updating my employment status but I simply forgot to respond to them. Today I check my Student Finance account and saw that I have been put on arrears and interest rate and also saw that I must have paid around 234GBP since April 2023.
My question is, what will happen when I will send them the employment status and all the proof the need? If I don't earn above the yearly treshold will I still have to return something from arrears?

Thank you!
