Mac 10.14.6 I've submitted to support.
I have a zipped version of v3.0.136 and it crashes at the same place (syncing rigs).
Is this due to my having some Ownhammer IR's saved in some Performances? That's the ONLY thing I've been doing new recently.
I HAVE booted the Profiler holding RIG to do an integrity check and all seems fine. But RIg Manager crashes EVERY time it tries to sync rigs.
