In Counter-Strike: Global Offensive, why the csgo trading inventory is currently unavailable? You can refer to the following:
The server crashed. In the game Counter-Strike: Global Offensive, a large number of players at the same time will most likely cause the server data to crash. When the server crashes, the trading interface will display that the inventory is unavailable, so players cannot view CSGO's inventory at this time. Just wait for the official server to be repaired.
