Can not Launch Unity Due to "Failed to load window layout"

Hi, When I try to change editor font Unity crashed (bug report case : 1162537) And now I can not launch Unity what ever I do. here a screenshot that dialog window I get. https://imgur.com/hXNl7Qu What can I do about this? other than re-installing Unity? PS: It was a fresh project. with no scripts in it. Only one sprite. PS 2: Opening a new project or other existing did not solve the problem. EDIT: apparently re-installing Unity did not solve the problem.
