I was able to get the plugin working again by making the following changes to \Plex Media Server\Plug-ins\Giant Bomb.bundle\Contents\Code\__init__.py
Look for "response = JSON.ObjectFromURL(API_PATH + '/chats/?api_key=' + ApiKey() + '&format=json')" and put a # sign in front of each line going down to the second ")" like link below.
Once the change is made you will need to restart your Plex Server for changes to take effect.
Live Streams will not work till this is fixed.
Once we get word this is fixed you can remove the # from each line so it should look like link below.
This worked for me.
