I found the way to fix the problem:
Open the gpedit.msc
In the left pane of the Local Group Policy Editor, click/tap on to expand Computer Configuration, Administrative Templates, Windows Components, Windows Update, and open Windows Update for Business. (see screenshot below)

In the right pane of Windows Update for Business, double click/tap on Manage preview builds to edit it. (see screenshot above)
Disable then Eable it
