IDE startup or Build process fail with error "Permission denied: listen"

Problem description

• IDE does not start with the following error:

  java.net.SocketException: Permission denied: listen
  

• Building (or syncing) a project doesn't work. It prints the following errors in the Build output window:

  Permission denied: listen

  Permission denied: listen failed

  

Solution

Disable Antivirus software or firewall (e.g. Windows Defender)

If you don't want to or can't disable the protection:

1. Adjust your Antivirus / firewall settings so that IDE default directories, installation folder, the process itself and project files are all excluded from the Antivirus / firewall scan. For instructions, see help article one and two.
2. Make sure the IDE is installed on a fast local drive and project files are not located on network drives
