Exact same issue here.
Analog Lab 1.1 AAX crashes Pro Tools 10 when deactivating the plug-in in any way: choosing "no insert," manually deactivating, deleting the track, closing the session. Deleting the AAX version and only using the RTAS works. Is this a known issue? Is it an issue with Pro Tools 11? (If so, it would make the plug-in essentially unusable, as AAX is the only option.)
