[OBI5] System.NullReferenceException (ProjectView.ContentView.SelectPhraseBlockOrStrip(EmptyNode node)

We got the following exception with a fresh installation of OBI 5, while recording or just after stopping to record (the end user isn't sure).
The project file is not corrupted, the user could resume editing without problem.

Is that a known issue, any precaution to prevent it ?
Thank you
