Yes it’s a huge problem.
Did you read the contract that your family and your high school counselor signed? They also could likely ban your hs from future EDs.
That you didn’t realize this shows me that maybe you are not yet ready for college - maturity wise.
It looks like you have until November 10th so if you have a portal, go on it and see if it allows you to change from ED to EA.
Otherwise, you need to email your admission counselor and let them know you need to change from ED to EA. They won’t ask you why but if they do, let them know you’re unable to be bound due to financial considerations.
Good luck.
