To avoid any 1619 error during installation, you need to exclude CD drive (physical/virtual) from antivirus real-time scan or wait for the real-time scan to scan all files in installation ISO media.
MSI error 1619 means that the installation package could not be opened:

Problem Cause

Antivirus McAfee was blocking SqlLocalDB.msi (or other MSI included in ISO) until it has been scanned.
The file is locked by AV so MSI Installer considers it as not accessible.
Then installation failed with MSI error 1619
