ERR_UNSAFE_PORT (-312) loading 'http://localhost:4045/'

[FedericoHeichou]

Describe the bug
Today opening Lens I got this error:
ERR_UNSAFE_PORT (-312) loading 'http://localhost:4045/'
Seems like it is not a firewall problem, but just Lens seems scared to contact that port (like some browsers, where you should add something like --explicitly-allowed-ports=4045)

To Reproduce
Steps to reproduce the behavior:

1. Open Lens

Expected behavior
Lens should connect on its server

Screenshots

Environment (please complete the following information):

• Lens Version: 5.3.2
• OS: Windows
• Installation method (e.g. snap or AppImage in Linux):

Logs:
When you run the application executable from command line you will see some logging output. Please paste them here:

info: [WINDOW-MANAGER]: Loading Main window from url: http://localhost:4045 ...
error: [WINDOW-MANAGER]: Failed to load Main window {"code":-312,"desc":"ERR_UNSAFE_PORT"}
error: Loading main window failed {"error":{"errno":-312,"code":"ERR_UNSAFE_PORT","url":"http://localhost:4045/"}}

Additional context
Actually I didn't try to reboot my system, later I will try it but I still want report it because I think it could be useful for someone else or other reasons
