version 3.0.311 breaking usage of cshtml razor helpers

[JSystemsTech]

Hi, I am running a .NET 5 (Core) application. When I updated to version 3.0.311 all my razor views started breaking on code like: <div>@Model.MyValue</div> so I was unable to use the builtin razor '@' prefix helper commenting out @addTagHelper *, WebOptimizer.Core in _ViewImports.cshtml fixes that issue but of course breaks adding bundles to the page.

the only imediate solution I found was to downgrade back to version 3.0.307

not sure if anyone else sees this or not but i thought I would bring it to your attention
