Hello magalie cadiou,

Perhaps it's worth checking the filters first and that they are showing 'Show all projects'

If this doesnt help., please post a screenshot, so that we can see the projects view.

Hey
I've checked the filters, reboot the soft + my computer...
I attach a screenshot, I've just reopened the red project, and the black one was the only one that had stayed in the list.

Hello magalie cadiou ,

If you select 'Open Project'- Navigate to the project  and open in Studio

Then close and reopen Studio, does the project appear in the list?

Where are the projects stored? Locally or in the cloud?

Studio isn't really designed to handle projects in the cloud. If there is an interruption for instance in the internet connection, this will cause issues.

If the projects are stored locally and you dont use external drives, cloud storage, then we need to look at this in more detail.

Yes , it does appear in the list after reopening. All my projects are stored locally, nothing external... The empty project list doesn't make any sense!
