Error "Method '<Clone>$' in type " on Start when loading some Plugins

Hi All,

I am trying to set up the latest version of nopCommerce 4.40.4 on a local IISExpress and am getting errors related to certain plugins. The first plugin which fails is "Misc.Sendinblue" but a number of other default plugins also fail in the same manner.

The error is as below :
"Unable to load one or more of the requested types.
Method '<Clone>$' in type 'Nop.Plugin.Misc.Sendinblue.Models.SendinblueMessageTemplateListModel' from assembly 'Nop.Plugin.Misc.Sendinblue, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.
Return type in method 'Nop.Plugin.Misc.Sendinblue.Models.SendinblueMessageTemplateModel.<Clone>$()' on type 'Nop.Plugin.Misc.Sendinblue.Models.SendinblueMessageTemplateModel' from assembly 'Nop.Plugin.Misc.Sendinblue, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not compatible with base type method 'Nop.Web.Framework.Models.BaseNopEntityModel.<Clone>$()'.
Method '<Clone>$' in type "

I can workaround the issue by commenting these plugins out of plugins.json but really wish to get to the bottom of the issue as I may require some of these plugins.

I looked for similar issues so have tried setting full permissions on the Nop.Web folder for my user account which has not helped.

Thanks,
