KotlinNullPointerException on opening project programatically

I keep getting a lot of exceptions when I'm opening a project programatically. Also when the project opens the left side bar with files list won't load.

It fails when I invoke this method

ProjectManager.getInstance().loadAndOpenProject(configuration.projectLocation)

It starts with this exception in the stack trace below. Please refer this link for all the stack traces. https://pastebin.com/N6Naxga7
