Windows WSL2 Linux Local Project on WSL Filesystem Does Not Load

### Apache NetBeans version

Apache NetBeans 13

### What happened

When you create a local project from the WSL2 (windows subsystem linux) file system on windows, everything is accepted but then NB fails to load the files, for example my path to the project folder on windows WSL is

\\wsl$\Ubuntu-18.04\var\www\project

### How to reproduce

install WSL2 on windows 10 and then install ubuntu server from Microsoft store

new project - with existing sources use the WSL2 path

\\wsl$\Ubuntu-18.04\var\www\project

project does not load files

### Did this work correctly in an earlier version?

No

### Operating System

windows 10 home

### JDK

java version "18.0.1.1" 2022-04-22 Java(TM) SE Runtime Environment (build 18.0.1.1+2-6) Java HotSpot(TM) 64-Bit Server VM (build 18.0.1.1+2-6, mixed mode, sharing)

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

This works on a few other IDE's i have tried, not seen others fail yet

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Reproduce the issue on Windows 10 with WSL2 Ubuntu 18.04, Apache NetBeans 13, and the provided \\wsl$\Ubuntu-18.04\var\www\project path. Start by tracing how a New Project with Existing Sources loads files from that path. Done means the project accepts the WSL2 location and its files load in NetBeans.
