There's a typo in an exception message:
CWWKF0004E: An unknown exception occurred while installing or removing features. Exception: java.lang.IllegalStateException: Method called outside of provisioining operation or without a registered service
It looks like this can originate from FeatureRepository or SubsystemFeatureDefinitionImpl.
