Cant Run CSGO

[Flipper]

So i currently am running on Sandboxie version 5.14 64 bit and my processor is AMD Radeon Software Version 16.9.2

Now the problem i have is trying to run a steam game such Counter Strike Global Offensive, and every time i open up steam with sandboxie and then try and run CSGO... the program says that it is running but then doesnt even show me the game
