Windows 10: Error code: Wsl/InstallDistro/E_UNEXPECTED - Catastrophic failure

I am facing an issue with installation of Ubuntu 20.04 in my wsl. I have earlier installed WSL without any issues on my PC and was running fine with ROS1 and ROS2. But when i tried to uninstall a python verison, it show how corrupted the ubuntu. so i unregistered the older version. And now trying to install new one. But i doubt that the old files are still in my system as I can see the older version of ubuntu in my program and I am not an admin of the PC. But i have admin rights.What I did was as follows:wsl --update --web-downloadI used --web-download as without arguments was not working.Then

Microsoft.Net Catastrophic failure( 0x8000FFFF(E_UNEXPECTED)

I was just playing a video game(Guilty Gear Strive) and this Error came out of no where.

How do I fix this or should I even be worried in general?

Install WSL issue

I would like to install WSL because linux distros in Hyper-V are irritatingly slow for my GPU, so I though to get better performance with WSL, with which I have 0 XP.

Install fails with:
Code:

Error code meaning:
Code:

I have installed\enabled the following optional features:

1. Hyper-V
2. Virtual machine platform
3. Windows Subsystem for Linux

There is no network issue, I tried with firewall disabled.

Any hints are welcome.

Hi Paty,

• Have you tried to use the USB Drive and create a new folder on a different PC?
  
• What troubleshooting steps have you tried so far to resolve the issue?

We look forward to your response.
