Error in IDE when opening project in "this window"

[nsutcliffe]

I had three projects open in IntelliJ. Whilst within one project, I wanted to swap to another project. I used the project drop down to select the project, IntelliJ gave a pop up box asking me if I wanted to open the project in a new window or in "this window" (i.e. the current project). I chose "this window", and then I got an IDE error, this is the stacktrace:
