Eufy Component of core causing error message.

The problem

I have been receiving this error across multiple versions of HA. Some versions of HA (the first March 2024 version for instance) cause all of the devices in the Eufy integration to no longer be recognized. Restoring to a previous version of HA fixes this. This error, however, has been consistent, even when the Eufy devices are properly recognized.

KeyError: 'access_token'

According to fuatakgun](https://github.com/fuatakgun, the issue "issue is coming from eufy component of core not eufy security custom component".

It seems every other iteration of HA causes Eufy to lose the devices.

I'm seeing this same issue as well; my Eufy components work and the integration is functioning fine. But I still see this in the system notifications after every reboot
