UI Designer has caught an exception

Hi Folks.

I have this issue using C4C SDK when i edit custom screens ( OWL or QA ):

"UI Designer has caught an exception. The BO Browser failed to initialize, there might be an error in connecting to backend system."

Due to this error message, i can edit the screen but i can't save it.

Any tips about this issue? I raised a ticket into C4C Help Center but i appreciate your thoughts about it please.

BR,

Mauricio.
