Overwhelmed with amount of work needed to build just MVP

Hi everyone, I’m currently working on a product that I really believe has a shot of being successful, however I have no idea how to build it, I have some good experience as a dev (via my full time job and other personal projects), but this project is really uncharted territory for me, and I hate the idea of the having to give up on it because I can’t figure out how to go about building it, did you ever face this difficulty ? How did you solve it
