Hi,

Try performing a repair upgrade.

To install bash, open a Command Prompt (Administrator) > type lxrun /install > hit Enter.

Note: The command will ask for a username and password for the user account in the Bash environment.

You may also skip the account setup during the installation of bash, open a Command Prompt (Administrator) > type lxrun /install /y > hit Enter.

Note: The root account will be the default user account without a password.

Best Regards,

Tao

Thank you very much

I got it fixed some time ago and forgot about this thread.

In my case, some windows updates are failed and manual installation fixed it.

But still, much thank you.
