Unable to set-version to 2 after setting it to 1 (0x80070050)

Repro Steps

I encountered the following error when starting up WSL2 :

WslRegisterDistribution failed with error: 0x80070050

Following online guides I attempted to reset my WSL back to version 1 and then to 2 again as this apparently fixed the issue.

Having now set my WSL to version 1, I now encounter this issue when attempting to reset to 2:

wsl --set-version Ubuntu-18.04 2

Conversion in progress, this may take a few minutes...
For information on key differences with WSL 2 please visit https://aka.ms/wsl2
The supplied install location is already in use.

I would like to use --set-version instead of reinstalling as it seems my data is still store in my ext4 file, and in the Apps list my Ubuntu size is at 20GB. Would be a huge hassle to restore the environment.

Expected Behavior

Be able to set version to 2

Actual Behavior

wsl --set-version Ubuntu-18.04 2

Conversion in progress, this may take a few minutes...

I get the following error when trying to capture logs, and oddly my feedback hub is missing, when I try to add it via Apps-> Optional features it's nowhere to be found in that list either

C:\Users\zhang\Desktop>wpr -start wsl.wprp -filemode

    Error code: 0xc00ce584

@assist726: It looks like the wsl.wprp file you downloaded is corrupted, can you validate that its content matches this ?

[assist726]

@OneBlue Apologies, did redownload and has seemed to work this time.

@assist726 : Based on the logs it looks like the VHD already exists.

Can you validate if there's already an ext4.vhd in C:\Users\{username}\AppData\Local\Packages\{app family name}\LocalState

If you don't know the app family name, you can get it with powershell:

Get-Appxpackage | where {$_.Name.contains("Ubuntu")}

[assist726]

@OneBlue Yes there is already a ext4 in the location

That's why the conversion is failing. I'd recommend making sure that you've backed up all the data you need from that vhd and then either moving it to a different location or deleting it and then try the conversion again.
