I cannot access wsl files from Windows

[Beanbit]

I know this is a duplicate issue. I've tried many of the suggested fixes in #4260 with no success.

Environment

Windows build number: *Win32NT  10.0.19041.0 Microsoft Windows NT 10.0.19041.0*
Your Distribution version: Release: Ubuntu *Release:  20.04*
Whether the issue is on WSL 2 and/or WSL 1:  WSL2 *Linux version 4.19.104-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Wed Feb 19 06:37:35 UTC 2020*

Steps to reproduce

I've tried 3 ways to access wsl2 Ubuntu files in windows.

Add Network Location with \wsl$\Ubuntu-20.04 as the address.

\wsl$\Ubuntu-20.04 in file explorer address bar

explorer.exe . in wsl.

Expected behavior

I'm expecting to be able to access wsl from windows.
With Add Network Location I was expecting it to mount a network location to the \wsl$\Ubuntu-20.04 directory
Navigating to \wsl$\Ubuntu-20.04 should open that directory in file explorer.

With explorer.exe . in wsl I'm expecting a file explorer window to open to the current directory.

Add network location should mount a new folder in windows to that directory.

Actual behavior

Using the file explorer address bar says there is a network error.

Using Add Network Location gives the following error

explorer.exe . just opens up explorer to my documents folder.

Please note this is while WSL is running
PS C:\WINDOWS\system32> wsl --list --verbose
NAME STATE VERSION

• Ubuntu-20.04 Running 2

I would suggest you try this:

1. save your work, and wsl --shutdown in a console with admin
2. re-launch Ubuntu
3. powershell.exe start . in Linux instead of explorer.exe
4. or Win+R, then run \\wsl$

I've tried these and did not have any success. Option 4 gave the the same error as the second screen shot above and option 3 gave me the following error:

start : This command cannot be run due to the error: The network path was not found.
At line:1 char:1
start .

I guess 9p has some problem. Can you try dmesg |grep 9p in linux?
Here is my output:

[    0.363323] 9p: Installing v9fs 9p2000 file system support
[    0.363336] FS-Cache: Netfs '9p' registered for caching

possible the same with #5307

@licanhua #5307 was indeed the problem. I wasn't very deep into my own setup so ended up uninstalling WSL completely and reinstalling. Problem fixed. Thanks for your help.
