Help Needed: Aether FPV Archetype Build Not Starting

Hey, Im building the Aether fpv Achetype and it is such a solid build but for some reason its not working. when i plug in the battery i only see lights and dont hear any startup sounds. I went into betaflight to try and start the motors but nothing would turn. This is my first build so there is a high chance i messed something up but if anyone can help that would be great!
