I had that same issue yesterday with Element 2.2 when i was trying to open recent project. So I did a full reboot and then opened the project, but not from the recent project list. Not sure if that helps you, but that did the trick for me.
I often have crashes with plugins in the CC2015, the workaround seems to be opening AE, creating a new comp, adding a solid and applying the plugin causing problem, then opening the project you wanted to. It works 100% of the time here.
