Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions.

I am unable to figure out why, any help please ?
>Solution :
In your error you can see it says
System.ArgumentException: '6.1.6,6.2.3' is not a valid version string.
And indeed your problem is actually in this file: https://github.com/MohamedBenighil/WebAppWithDatabaseDemo/blob/055037f9f22bdac6db2edadeab01b412f3c4dca2/WebApp/WebApp.csproj
where you have that invalid Version string in your package reference:
<PackageReference Include="System.Management.Automation" Version="6.1.6,6.2.3" />
