Hi @Leonardo

Could you clarify that you are trying to create new project and not open an already existing one?

Hi @Leonardo,

Can you please provide us the studio log files?
Also the specified content of the project.json is part of BlankProcess1 and not the reported BlankProcess2 (which caused the error). Could you specify the content of the BlankProcess2 project.json?

even i am facing similar issue till today morning it was working fine but now i can’t create or open any file.

and can’t even upload log file as try to select file my browsers shut down… this happens in all browsers.

The problerm was the antivirus. I deactivated it and now it works
