Apple Home app crashes when I open Automations

A few days ago, the Home app stopped responding. The screen would go black, and the app would close unexpectedly.

I updated to the latest version of iOS, checked for updates, restarted the device, and even removed my HomePods to delete the app and reinstall it, but the result is always the same.

After running some tests, I deleted all my Scenes and Automations. Suddenly, it started working correctly again. Then I discovered that if I create automations directly in the Home app, it works fine. However, if I add an automation from a third-party app (like Controller for HomeKit), the app freezes, crashes, and I can’t open it again. I have to uninstall and reinstall the app. And if I don’t remove those third-party automations, the app freezes whenever I try to access the Automations section.

The behavior is the same on iPhone, iPads and Mac OS.

I have more than 100 connected devices and many automations that I can’t configure solely with Apple Home, so I rely on Controller to make them work. I’m surprised it worked flawlessly for years, and I haven’t found anyone reporting a similar issue.

Any ideas? I’d prefer not to have to delete my Home and start from scratch if possible =)
