Wedding Photographer Unresponsive, 5 weeks before the wedding

Hi! My fiancé and I hired the same photographer that did my sisters wedding in 2020 because she was great and I know her from college. We signed the contract in Feb 2021 for May 21st 2022 wedding and I haven't heard from her since. I reached out on Monday April 11th because I realized its 5 weeks form the date and we haven't talked yet. I didn't hear back and texted and called her on Wednesday April 13th and got no response. I would give her more time to respond but I'm worried that since its so close to the day that if she never responds we wont be able to find anyone else. Has this happened to anyone else or have any tips for what I should do?
