Source Generator ObservableProperty Debugging / CS8785

New to using ObservableProperty. I have an app that runs just fine, yet I'm getting a warning:

Severity	Code	Description	Project	File	Line	Suppression State
Warning	CS8785	Generator 'ObservablePropertyGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'ArgumentException' with message 'SyntaxTree is not part of the compilation
Parameter name: syntaxTree'	APP C:\PROJECT.csproj	1	Active

How do I find out where the problem is?

I undid all my changes and redid them and now the warning is gone. It was exactly the same changes. 🤷‍♂️
