Hi, you weren't specific about what you were doing when it crashed, but here's my experience and what I figured out.
Every time I clicked on the Smart Controls button (left of the Mixer button), Logic Pro immediately crashed with a crash report. I reported it to Apple and here's the ADDENDUM info I sent them later.
The crash ONLY occurs if the selected track contains a Session Player, in my case, Session Keyboard.
Could that be the cause of your crashes, too?
As soon as a non-Session track is selected, the Smart Controls button worked as expected and Logic Pro doesn't crash.
Apple's been alerted, so no doubt, they're already looking into it.
Hope that helps,
John
