Description:Message: The route template 'getavatar/{avatarguid:guid}/{filename}' is already registered.
Parameter name: descriptor

Exception type: System.ArgumentException
Stack trace:

Thanks Dmitry

Removed the Xperience Library Nuget package and found there were a few manual CMS References from Lib, Cleared those out and it worked well.
