Weird Error message with empty projects

Hello everyone I'm getting this error message. I have tried everything. It happens with a empty project as well.

I tried a fresh install, deleting all files in the project. Reverting the layout. etc But it just sit there. This was first noticed with Surforge, but it is constant now. The error grows when I add surforge to the project which makes me think this more of a unity problem.

I appreciate any help. Iam getting this message:

Does anyone know what could be causing this and how to fix it?
