Your WSL installation appears to be in a bad state. Can you try running the following command to reinstall WSL (elevated powershell) and see if that solves the issue?

Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/triage/install-latest-wsl.ps1" -OutFile install-latest-wsl.ps1
Set-ExecutionPolicy Bypass -Scope Process -Force
.\install-latest-wsl.ps1
