Roslyn not finding a referenced package

Hey there Over the past months I've really fallen in love with writing my own Roslyn code generators. My Discriminated Unions library heavily relies on this, and because I have noticed that some of my generators share the same basic code, I wanted to write a simple library I could use in my various projects : https://github.com/code-of-chaos/cs-code_of_chaos-generator_tools The issue now is that I try and use the uploaded nuget package in the consumer Roslyn generator found here: https://github.com/AterraEngine/unions-cs/blob/core/src/AterraEngine.Unions.Generators/AterraEngine.Unions.Generators.csproj Within the IDE (rider) everything seems to be fine in the generator's code as it discovers all the types within the package and I'm able to use them when I'm writing code, but whenever I try and use the generator no code appears and I get the error : 
System.IO.FileNotFoundException: Could not load file or assembly 'CodeOfChaos.GeneratorTools, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.
File name: 'CodeOfChaos.GeneratorTools, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null'

I've been stuck at this for a few hours now, and I'm lost at where I've created some issue

I haven't created a new latest nuget package for AterraEngine.Unions.Generators yet as the code isn't working. Within the project there is a Sample project AterraEngine.Unions.Generators.Sample which when I try and build outputs: 
1>CSC: Warning CS8785 : Generator 'UnionGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'FileNotFoundException' with message 'Could not load file or assembly 'CodeOfChaos.GeneratorTools, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.'.

AterraEngine.Unions.Generators is on the latest uploaded version of CodeOfChaos.GeneratorTools which is 1.1.0 csproj file of AterraEngine.Unions.Generators : (had to split the file because of max message length)
