It said "a degree in a relevant field", what major did you study? you can try to relate your major and your experience to the new position. I'm sure you have gained a lot of skills in your prior position or major, which will apply to your new position. All you need to do is to edit your resume, make it related to your new position, and apply for it! Who knows maybe there is no other candidate and you will be hired since you are the only one. Goog luck!
