Win10 LTSC here, when I create new project "PixelboxProject", the program assumes the project folder is "Documents\PixelboxProject" and just refust to create the project, unless I make a folder in "Documents\PixelboxProject" first, it seems the program just unable to make a new folder properly so it keeps reminds you to select a valid folder. I'm running in Administrator account so I can confirm this is not UAC issue.
