Upgrading to .net 5 assembly is missing framework version

I am upgrading my project to .net 5 and have the strangest error at time of build.

 <ResolvePackageAssets 
  ProjectAssetsFile="$(ProjectAssetsFile)"
  ProjectAssetsCacheFile="$(ProjectAssetsCacheFile)"
  ProjectPath="$(MSBuildProjectFullPath)"

I am using the package from SimplyCommerce to create a modular web site and I get this error.

Severity    Code    Description Project File    Line    Suppression State
Error   MSB4044 The "ResolvePackageAssets" task was not given a value for the required parameter "TargetFramework". SimplCommerce.Module.PaymentPaypalExpress   C:\Program Files\dotnet\sdk\5.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets    241 

When I look at the assembly details I have renamed mine to warehouse crm but when I look at the target framework its showing blank. Even though I had previous set it .net 5 is their an error in the tooling im running the latest visual studio when I double click the error it takes me to this file

C:\Program Files\dotnet\sdk\5.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets

Before you ask .net 5 is install on the target machine.

This is the csproj file of the offending libary you will see their is no framework version because it is a razor sdk libary
