Hi All,
I’m running HAOS on a RPI5 and recently I noticed the following error in the logviewer:
2025-06-02 18:26:47.068 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved (None)

RuntimeError: dictionary changed size during iteration
There is no automation or something else that triggers every 30-40 seconds, it looks it happens at pseudo-random intervals.
I don’t have any idea where too look for this problem, someone who can give me some hints?
Any help greatly appreicated!
