Here is how to fix it.

It looks like this issue affects only Windows 10 users with non-English language. To fix the issue, you need to switch the operating system language to English, reboot the OS and then re-install Bash.

Here is what to do.

  1. Download English MUI/Language Pack from here: MUI language pack for Windows 10 build 14316 – direct links. If you are running the build version other than 14316, you can just install the appropriate MUI pack using Windows Update as described below.
  2. Press Win + R keys together on the keyboard to bring up the Run dialog.

  3. Type the following in the Run box:

    Press Enter.

  4. The "Install or Uninstall display languages" wizard will appear on the screen.

    Click the Install display languages button.
  5. On the next page of the wizard, click Browse and pick the *.cab file of the MUI language you downloaded. In these screenshots, there is a Russian MUI package. In your case, it will be an English package.
  6. Click the Next button and wait till it is installed. This can take a considerable amount of time and disk space.
  7. To switch to the installed language pack for your user account, you have to open the following Control Panel applet:
    Control Panel\Clock, Language, and Region\Language
  8. Click "Add a language" there and add the English language you installed:
  9. Click the Options link on the right side of the installed English language.
    There, you will find the ability to activate English as the main display language.
  10. Restart Windows 10.

Once this is done, follow these instructions to install Bash once again: How to enable Ubuntu Bash in Windows 10. Now, it will be installed properly.

After doing this, you can set your previously used language again in Windows 10. Everything will work as expected.
