Resolution Note:
The root cause of the issue is a missing module (com.unity.modules.animation) in the project manifest (Packages/manifest.json). On Unity 2021.x (and newer) you will not get the *recursion error*; instead you get a compilation error which is the error you get for any missing reference. On Unity 2020.x and older the error message is misleading; unfortunately detecting this scenario and not emitting the misleading message is not a trivial task so we decided to not pursue improving this for now. If we ever get similar reports we may reconsider.
