Hello,
If it has been less than 30 days from deletion and you haven't emptied your Trash the project can be restored.
If you go into the space where the project was deleted from and click on the Trash icon found in Header, you'll see a list of trashed projects, click Restore, on the right side of the project.
The project will be moved out of the trash and back into the space, allowing you to open the project again. Please note that any project in the trash for 30 days or more will be permanently deleted.
Thanks,
Karen
