No shadows and sounds in shipping mode

Hello :wave: ! I made a little game with UE 4.27.2 and C++ but I have a problem. As I said in the title, I have no shadow and no sounds when I package my game to shipping mode. However, I can package in development mode, the game works perfectly. I tried to check “Cook everything in content directory” but still doesn’t work. I also tried create a new project and package it, it works. I need help, please :grinning:.

My specs :

CPU : I5-3210M
GPU : AMD Radeon HD 8750M
Storage : SSD Sata 1 TB

Problem fixed ! It was the folder of my game in %localappdata% from previous versions of my game :grinning: .
