Loader fails when circular dependencies exist within an application

[bizob2828]

Expected Behavior

When running an application that has circular deps with import-in-the-middle, it should handle this accordingly.

Actual Behavior

It silently fails in pre Node 20, and in Node 20 errors with

  dep1()
  ^

ReferenceError: Cannot access 'dep1' before initialization
