Alarm Control Panel Error on reboot

Hi, has anyone else experienced a problem with the manual alarm control panel not setting up when rebooting? I get error messages “Error adding entities for domain alarm_control_panel with platform manual”. I have attempted to delete the config, reboot then add the config back in with no change to the error. I did notice in my UI the card that shows the alarm state was stuck in “pending”. I deleted that as the entity alarm_control_panel.alarm did not exist. No difference made.

I have logged an issue which has not received a response at this time.

Many thanks for any suggestions.

One additional piece of information I noticed the last time I reloaded the config I also got an error in the traceback “KeyError: ‘previous_state’” even though the entities don’t exist.

Workaround was to delete the config, restart HA, then add back the config with a different alarm name.
Was alarm_control_panel.home now alarm_control_panel.home2

Created the entities with the new name.
