According to your error message, based on my search, it can occur if you have no permission on the C:\Users\ "username" \AppData\Local\Temp folder. To troubleshoot this issue, you can grant yourself or everyone full control permission via the following steps.
- Going to Properties > Security on the C:\Users\ "username" \AppData\Local\Temp.
- Giving “Everyone” the Full control permission.
- Reinstall SQL Server again.
In addition, please make sure that the Windows Installer service is running. Download SQL server 2019 from this link again, Run the setup as administrator.
