CLion fails to successfully open a new code project created with an Editor that has been set to use CLion as the preferred source code accessor.
This requires that the Editor be already set to use CLion as the preferred source code accessor. This can be accomplished by opening an existing project in the Editor and setting it to use CLion.
CLion attempts to open the project, but several error messages are displayed:
CLion successfully opens the new project.
