There is nothing anyone can do on this public internet forum that you have not yet done for yourself.
If the direct deposit could not be made by the processing bank then they should mail you a check to the address on your return. Did you move since filing ? If so check with the processing bank to update your address if you can. If not then the processing bank probably sent the money back to the IRS which is where the third stimulus payments are sent from as well as any advance payments of the CTC.
Mail in a form 8822 ASAP to the IRS if the address on your return is no longer good : https://www.irs.gov/forms-pubs/about-form-8822
