Entries Not Writing to core.config_entries

Recently in 2025.4, new entries added to existing integrations disappear after a reboot/restart. I have tested with private ble integration, google conversation ai integration, and workday integration. When adding a new entry to these integrations, they appear in the UI, but when I check core.config_entries they are not present. When home assistant restarts, the entry is removed from the UI.

I posted this same thing as a bug report, but hoping I can get feedback from the community. I won’t be able to add any new devices until this is resolved.

A bit more info from this morning, I added a test workday sensor in safe mode and it persisted through a restart. So i’m thinking it may be related to one of my custom components?

I’ve figured it out. It was related either to the “Holidays” or “Meross cloud” HACs custom integrations. i removed those and now entities persist.
