ISSUE: Blocking call event loop during package initialization causes HA to hang

[chriswood1001]

Describe the bug Mail-and-packages freezes during initialization (after I successfully link my gMail account and select my folder + sensors). Home Assistant reports an event loop, freezes, and must be restarted. Home Assistant no longer boots with the last log entry on boot attempts being "2024-06-25 23:12:57.286 ERROR (MainThread) [custom_components.mail_and_packages.helpers] Error searching emails: command: SEARCH => unexpected response: b'7csp12957rwo;'" Removing the mail-and-packages from the custom_components directory allowed me to boot, disable and then remove the integration. 100% reproducable.

Environment (please complete the following information):

• OS: Docker
• Type of device: Dedicated server hardware, Xeon E-2386G x6 core, 64 GB DDR4
• Home Assistant version: 2024.06.4
• Docker
• Component version: v0.3.29

Additional context I had this working originally for over a year, upgraded mail-and-packages through HACS and had an issue (I forget what the issue was). As part of troubleshooting I uninstalled the package, restarted HA, re-installed this package and now am facing this issue preventing HA from booting. 100% reproducible.

I've linked it to gMail, see my directories, select "Home/Mail" (which is where I filter all my package emails). I've selected all sensors for Amazon, DHL, FedEx, plus the last two sensors regarding summaries.
