Hi,
You could try the following steps:
In the Admin PowerShell, type:

$LanguageList = Get-WinUserLanguageList
$LanguageList.Add("qad-latn")
Set-WinUserLanguageList $LanguageList -Force

Then go to Settings (Win+I) / Language settings, and just remove qad-Latn from there.

In addition, here are some posts with the similar issue with yours, just for your reference, you can try the method mentioned in them:
