It was all working fine until .net6 and today when I upgraded my .net framework to .net 7 Extent.flush started throwing this issue

Exception Message :

`Expression of type 'CompiledRazorTemplates.Dynamic.RazorEngine_b9f52b03346147f1a44ad78178672b4f' cannot be used for return type 'RazorEngine.Templating.ITemplate'

I'm also getting the same issue as of today. Worked fine Friday (10/03/2023) but not working now (14/03/2023).
