This issue has been opened as #5092 and #4929, But none of the solutions seems to work for me. I have even tried completely uninstalling WSL, Hyper-V and all kinds of virtualisation features. But none of them works. So I thought I'd open a new issue in the hope to get my issue resolved.

Thanks @Wizards-god.

Looking at the logs, I can see:

[   36.631216] EXT4-fs (sdc): VFS: Can't find ext4 filesystem
[   36.631819] ERROR: Mount:2683: mount(/dev/sdc, /distro, ext4, 0x0, discard,errors=remount-ro,data=ordered

Based on that, it looks like your distribution VHD is corrupted.

Can you share the content of HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lxss ? The path to the distribution VHD is under that key.

I did not know how to export individual keys, so just exported it and attached it here
VHD.txt

.

Ok, based on that I can see that the disk for ubuntu is in C:\\Users\\parja\\AppData\\Local\\Packages\\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\\LocalState. There should be a file named ext4.vhdx in that folder.

To recover its content the simplest I can think of would be to use wsl --mount, so something like:

wsl --mount C:\Users\parja\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\ext4.vhdx --vhd --bare

And then use fsck on the disk to try to recover its content (you can use lsblk to list the available disks)

Note that:

• If you don't care about the files inside that distro, simply uninstalling and reinstalling it should work
• wsl --mount --vhd is only available in WSL from the store so you'd need to install to use it

Thank you so much, I could recover all my files from the distro. Now it is working like before.
