Could you describe in greater detail what sequence of menu commands, shortcuts or buttons you are clicking on? It’s unclear, for example, whether you mean adding a file to the binder in an open project, or maybe even creating a whole new project.
Reinstallation is a good first step, but in this case you may also want to run through this checklist and reset your preferences. It is not uncommon for a crash to be a result of a bad setting, or even where the whole preference file has been corrupted by the system.
Next step is to create a new blank project and see if that works, and if that does, go on to try the template you wanted, if applicable.
