Problem opening main.scss in styling editor

Hi Mendix Community,   I am working on the learning path “Style your App with SASS” at the moment.   In one chapter, I need to open the “main.scss” file to add a partial. Unfortunately Studio pro just returns the following error message and I cannot see the content of the scss file.      I already tried to uninstall and reinstall Studio Pro, which did not help. I am using the app, which is given by the Learning path.   I also get an error message, if I try to open any page in the design mode:     Do you have any idea, where the problem could be located and what I can try to proceed?   Thanks a lot and have a nice day Malte

Thanks a lot, that is a great workaround! 


But is there a general problem with my Studio Pro, because normally this functions should be working, right?
