[Xposed Framework Modules] C3C076:
Thanks for the logs. This seems to be some kind of a glitch in Xposed framework iself that is related to preference handling.

Nothing can be done at GB side to solve this. You should upgrade to the latest official xposed framework for SDK22 (v73) in the first place.

AFAIK, there were also some new improvements regarding XSharedPreferences.
