Sitecore 10.4, NullReferenceException with GetRenderingParameters()

[fredlebel]

The regression is triggered by using Glass Mapper's function to get strongly typed rendering parameters.
Html.Glass().GetRenderingParameters<SomeGlassType>()

If the Glass type has a Url field:

[SitecoreInfo(SitecoreInfoType.Url)]
public virtual string Url { get; private set; }

Then GlassMapper ends up calling the following function in Sitecore.Kernel.dll:
Sitecore.Links.UrlBuilders.ItemUrlBuilder.Build()

In an earlier version Sitecore.Kernel.dll(16.0.0.0) this function would return string.Empty after checking if the item's path is null.
But in the newer version, Sitecore.Kernel.dll(19.0.0.0), an exception is thrown before reaching a similar check.

This seems like Sitecore tripping on the fake item created by Glass when mapping the rendering parameters in RenderingParametersModelFactory.cs.

Item item = Utilities.CreateFakeItem(null, renderParametersTemplateId, _sitecoreService.Database, "renderingParameters");

[girishsharma008]

Seems like issue related to glass mapper 10.3 library and upgrade is required.

@mikeedwards83 do we know when Glass Mapper support release planning for Sitecore 10.4

Thanks
