Vincent said their isn’t enough logging available to identify the issue.
But he also gave guidance to some others with a “Preinstalled App confusion” issue (related to ioDroid / F-Droid both with FP5 devices) that may help you:
As the iodé app / blocker shares the same system-level process as Preinstalled Apps, resetting the iodé blocker (from within the app) and then again doing the Preinstalled App > remove > reboot > install > reboot may solve it?
