@angealll From your screenshot I cannot tell what is wrong. You may be able to see where your issue lies by looking at the StudioLog.txt (after you enable the FilePublisher). Often when a project cannot build, you have changed something that has broken a piece of existing functionality. For example, a script method was changed to now have different parameters. If you are using source control, it is possible that another developer changed something in another project, and it cannot build by itself. You can isolate that by building each project individually and seeing which one fails.
