Same issue as documented by others. Seems Logos 7 is unresponsive and not opening since I did the latest MacOS update a few days ago. I get the "untitled" in the menu bar - I've followed the instructions as given in the forums and directed by customer support. Nothing has fixed it.
In a last effort to get this resolved, here is my log report attached.
