It did take a little while to load the first time because it tried to find an update for the part and a few subparts (some are still unofficial) and during that time the interface did become unresponsive for a few seconds, but it loaded just fine. Please elaborate on "crash" and please tell us what version/system you are running on, and what part, specifically, you have issues with.
