Hey @Sara Cheikh ,
Sorry to hear you are having issue to access to your file!
This usually happens when your access of this file has been edited, or the file has been deleted.
As the first workarounds, I recommend you to:
- Make sure you're logged into the correct account.
- Check if you’ve accepted the invitation to view or edit the file under the right account.
- Look in your deleted files to see if the file is there.
- Contact the file owner to request access again.
If these workarounds still don’t help, don’t hesitate to contact directly our support team by filling out this form: https://help.figma.com/hc/en-us/requests/new?ticket_form_id=360005944714.
