No port protection if application is launched twiced

• Version: 13.5.1 (but confirmed source code was not improved in the latest for this issue)

• Target: Windows (Windows 11) / MacOS (M Series)

What is happening is that during app startup, Electron Dot Net will inspect open ports to use as a setting for spawning the back-end server. There is a brief window between when the port number is selected, and when the back-end app actually starts up to utilize that port. If another app were to also start up during this time, then you get multiple instances attempting to spawn a back-end server using that same port and configuration. This results in a collision of port usage, causing the app to either crash or lock up.

Steps to Reproduce:

1. Launch built electron dot net application
2. Quickly launch a second instance
3. Note JavaScript exception that appears
