All transactions disappeared

Hello

I've been trying to remove an old credit card from quickbooks for ages and nothing I did worked, so in the end I unlinked the bank account entirely and just reconnected by work debit card. Unfortunately this seems to have deleted all of my reviewed transactions for the whole of 2023 to date! I didn't think this would happen as they were already reviewed and approved. Is there anyway to get this back or am I going to have to add all the previous transactions manually now?

Thanks
