Outlook 2016 freezes frequently since installing the new add-in 2.2

I have installed the new 2.2 add-in (no previous versions installed) on both laptop and desktop. Since installing, Outlook on both machines freezes frequently, requiring an End Process in Task Manager. The freezing doesn't appear to be connected to any particular function in Outlook; it just stops working. A couple of times Outlook has displayed a message that the Sugar add-in caused the crash and has been disabled. As soon as I re-enable, the freezing starts occurring again.

This is happening on two machines, both with plenty of horsepower running Windows 10. Anyone else having issues with the newly released add-in?
