Reproduce the failure with dwds 3.1.1, then trace package_config/src/package_config_impl.dart through package_config_json.dart and dwds/src/utilities/dart_uri.dart into AppInspector._initialize. Confirm the package configuration can be loaded without the mismatched-argument NoSuchMethodError during inspector initialization.
