Freezing is not crashing. FGU freezes when it is busy doing something. Usually this is not more than a second or so, FGU is also mostly single threaded, meaning it can only do one thing at a time. So, if you share a 6MB image and one of your players have really horrible bandwidth with dropped packets etc, then your computer (the host, freezes while it tries to serve the image to that one player. In most cases this shouldn't be more than 30-60 seconds, but it can grow exponentially depending upon the player connection. I think earlier you said that it had frozen for 10 minutes. And that would definitely indicate something is wrong, something like router throttling or other security applications getting in the way.
If you can isolate/reproduce what causes it or under what conditions it occurs, then we can help you trouble shoot more specifically. You might be able to try using a different internet connection (i.e. a phone hotspot, from your library, etc) and see if that resolves/helps.
