Hi,
I'm Sumit, here to help with your query in the Microsoft Q&A.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
Let me suggest an alternative installer. Please use the MSI package below for WSL and let me know if that resolves the issue.
https://github.com/microsoft/WSL/releases/download/2.6.0/wsl.2.6.0.0.x64.msi
I look forward to your response and am happy to work with you until we find a solution. Please keep me updated.
