@serdiyon what is the name of the install ISO you're using? This issue should be fixed by #604 in theelementaryos-6.0-stable.20210831.iso image.

If you're still using elementaryos-6.0-stable.20210810.iso or possibly the elementaryos-6.0-stable.20210823.iso file, you should re-download it from the homepage.
