Harmony crashing while rigging

The past few weeks have been fine but for the last couple of days it’s been crashing while rigging. It’s not a complicated rig. I’m not sure why it is suddenly doing it now. I haven’t changed anything on my computer. Any ideas?

It’s difficult to say, I remember Harmony crashing a lot if I used the node previews in 12 Premium, or if I had multiple camera views. Try to organize your workflow and file in a different way, maybe you can pinpoint what is causing the crashes and avoid doing it.

If you can give more information about your rig, It’s better. The problem can come from differents causes.
