Hi. I am having this exact same problem. I have an Ableton 10.0.2 session with many instances of Analog Lab 3 open. It had worked fine prior to this point, and I don't recall updating anything. Since this crash began, I have updated all of Analog Lab 3 -- to no avail. I read on several other forums that the solution may be reinstalling Live 10.0.1. That seems like a hassle, and Ableton doesn't have that version posted on their website. Also, many of the fixes for 10.0.2 were to alleviate AU units.
Arturia, please -- an update!? I can't even open my most recent session to edit changes without it crashing. It literally crashes the moment I open the session.
