Hey badi, look at the location where the file is being written, make sure it's not a prepicked system folder. If your destination folder is ok in the dialog box, the other thing to try is running Studio One as Administrator. I ALWAYS do that for all audio software and all Adobe stuff with Windows 10. In fact, I open Properties on the shortcut, go to the Compatibility tab and check the box for Run as Administration. That way it always does.
