Hello Everyone,
All of a sudden, I am experiencing an error when trying to save my logic app.


Logic apps isn't being really helpful here because when I click 'Open Operation' it just spins/does not complete or show any identifying information where I can possibly trace the issue.

I am not quite sure what has happened, also by looking at code view I can't really see anywhere that might be throwing the issue, but that could be down to my lack of knowledge!
I have even deleted the original Logic App, and recreated it from scratch, the error still appears when trying to make and change and save.
Has anyone experienced this before?
If anyone could guide me in the right direction I would be most helpful.
My logic app is quite large, with a few switch cases, but if I need to post the code in I will.
Many thanks!
