The project list is unfortunately lost every time Studio, if misfortune, does not find a project present in the project list, e.g. in the case of a connection breakdown with an external disk (where the projects are saved). Further to a connection interruption to the external disk,  the last active project list is unfortunately and automatically lost and replaced by Studio to a new "empty" project list. All your efforts to build a workable list of projects (project description, direct access, etc.) are then lost.

 In the previous Studio version (2017), it was possible to reactivate a previous project list by overwriting the "new" empty project list  automatically created by Studio by using a copy of a previous project list previously saved.

 This trick does not work anymore with Studio 2019. Is there a way to re-use previous projects list with Studio 2019 and not lose all your past efforts to create a workable project list?
