Visual studio blocking when loading solution

Hi,

I have web application that was running all night migrating data and logging errors in output with Debug.Writeline. After i restarted the Visual Studio and now I can't  load the solution. It is showing the output screen and failing to load it. When I try to load another solution Visual Studio is loading it with no problem whatsoever, only my solution that was running all night is not loading. I'm using Visual Studio 2017. Is there way to clear this output data? How can I load my solution?

Thanks
