TPS56637: Vout suddenly dropping to 0V

Part Number: TPS56637


Hi, I am using the TPS56637 as a 12V to 5V 3A DC-DC buck converter for a project. I have gone over the design with the datasheet and webbench multiple times with professors and TAs and did not find any issues there. I have also checked my solder work many times as well. However, during testing, Vout momentarily shows 5V before dropping to 0V and not showing anything else even when I reset everything. Are there any common issues with the TPS56637 that I may be looking over?
