Help, the FPGA-based electronic password lock cannot operate normally [Copy link]

Hi everyone, I am a student, I am learning about FPGA recently, and then I found a program for an electronic password lock on the Internet, I soldered the peripheral circuit myself, the core board is EP4CE6E22C, and the soldered buttons have pull-up resistors, but after connecting the program, the two light bulbs are on, and the buttons are unresponsive. What is the problem? The program is in the link. Please help me, thank you!!
