Yes, it plays now, but I can't really tell what you're doing when that error message pops up. Unfortunately, in my experience "Circular Structure" is a warning that usually pops up when a Logic/GB Project has become corrupted. I can't say for sure if your Project is corrupted, and if it is whether it was in response to something you did or just general file corruption..
You could try three things:
- Do a hard computer shutdown/restart
- Try what you were trying to do [editing Takes] in a new fresh Project with new recordings, and see if it works as expected there
- If the problem Project is important to you, you could try creating a new fresh Project from scratch, same Tempo, duplicate all the tracks [same instruments/presets, etc], and then Copy & Paste all the Regions from the potentially corrupted Project into that, and see if things work more reliably there.
