USD Lights cause crash and black viewports

Testing out USD and 19 beta 2 states fixed issue with lights ( - Addressed issue with using 3D lights in USD). But, I didn't see issues with 19 beta 1 version. But, now adding a USD Light into the USD Merge either causes Fusion to crash and/or causes viewports to just show black. Even disconnecting the light does not cause the viewport to render normal. Just stays black. Absolutely useless now to add lights to USD comps. This is for Mac version. Not sure about Windows.

It wasn’t this issue. Which issue it was… hehe, good luck finding out. BMD puts these notorious ”fixed an issue” notes into release docs but never tell which issue out of possibly many it was, because why the hell make it useful for users, right.
