Hi,
Please open a PowerShell window (admin) and run below command. Ater that, try it again to see if it helps.
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
If it does not help, open a command prompt (admin), continue with the following:
wsl --install
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
wsl --set-default-version 2
