Grasshopper File Error

Hi there. I have just installed Rhino 5.5.2 (5F85) and after saving a Grasshopper file I get the error below on every step. I am working on a MacBook - Mojave 10.14.2

I also was unable to find the autosave location mentioned on the error. It’s not a hidden folder either.
Do you have any ideas what could be causing that?

Thank you, Raquel

Same for me. Impossible to work correctly… every change I make in a number slider makes it appear.
Rhino 5.5.3 for mac, MacBook Pro, Mojave10.14.4

Please help !

I am not able to reproduce this issue on my machine. Can you please provide the definition and steps to reproduce this?
