Description

In Home Assistant App we access realm from the Widgets extension and since iOS 18 betas, when accessing Realm directly from the AppIntentProvider it is now crashing with 'Realm accessed from incorrect thread.' while if dispatched in main queue the issue does not happen.

BUT

If dispatched in the main queue then it crashes in iOS 17

Home Assistant PR with the workaround used to prevent that:
