Checked the concern reported by Ms. Yolani Gaid, they were not able to access ISAI, the error message says insufficient memory or disk space. I checked the memory of the local drive and it's not full, tried to execute query and the database is not accessible. Reported the issue to Jupiter  for further isolation and they advised to restart the server. I consulted this action with Arvin first, and he suggested restarting the SQL Server only. After the restart, the database of ISAI is now accessible, I also run the backup for the database.
