Intellij IDEA pluggin cannot be run

I am new to Intellij plugin development. Currently I am working on a project in creating a plugin to Intellij IDEA. When I click on the run button, it builds successfully and shows me the first window of the new IDEA but when I click on Open new project it gives me these errors and exceptions.
