Can not operate LCD in stm32l476 discovery board?

[BQuoc.1]

Currently, I am following a video to operate LCD in stm32l476 discovery board. So, I downloaded this code (07.5_L4-LCD) then it run well. But when I tried to create my own project following this instruction but it fail. I also looked and open file.ioc in example code to see how they configured hardware, but it could not open(it seems the it is compiled from other version of STMCUBE IDE) .Could anyone give me some suggestions?
