I would attend interview since u say income is solid and getting a new interview (later on) is sometimes difficult. If interview is successful , she waits for suspension to be lifted. She shouldn't let the embassy keep her passport at this interview. she can provide it when they do issue the visa later
On top of the need ,perhaps, for another medical exam, be prepared to update the I 864, with 2025 tax returns and W2 for the year as after the 15th of April , those will be needed

How long will the suspensions last?
The proclamation provides no expiration date. It directs the Secretary of State, in consultation with the Attorney General, Secretary of Homeland Security, and Director for National Intelligence, to report to the President within 180 days, and every 180 days thereafter, whether the suspensions should be continued, terminated, modified, or supplemented.
