Hello,

Is it Ok with new workspace? Did you get this error when you start the studio with new project?

Create a new workspace.

Import the project from the workspace and check it.

If you face the same issue import the project without .metadata,.JETEmitters,.Java.

 Can you please clarify in which Talend version/edition you are? Have you tried to re-install your studio completely to see if it works well?

Hi! I faced the exact same problem, but managed to fix by clicking on "manage connection" and reseting the workspace folder.
Just wanted do leave here this possible solution as well.
