A common issue faced by Astroneer players is that the EXO query platform will have an inactive error when players attempt to interact with it. The item is used in the CHEER Project Salvage Mission, EXO Salvage Initiative, and EXO Automated Mass Production Production. These are all in-game events available for a limited time, and when players tried to start a new game for these events, their mod didn't work. When a new event happens in Astroneer and you want to use the item, there is an easy way to fix it. Make sure that the event you want to participate in the game is still running, as it will not work if the event is over.
For those who are more fortunate, the fastest way to fix this is to pick up the item and then put it back. It's a quick and efficient method of making sure the platform is working for you.
The second method is to reload your save and try interacting with it again. Sometimes going back to the menu, or even closing the Astroneer app completely, is an effective method of resolving this issue so that you can start interacting with it again. Some gamers even recommend starting a new game over from scratch before trying to use it. While it can be a bit of work, it's a good way to make sure you're attending the event.
Creating a brand new game file should be the last effective method. If you are still having issues with the EXO Query Platform, you may want to check all files with the game or give it a new reboot on your hardware. You may not have downloaded all of the game files, which is causing you complications.
