Issue:
Android Debug Bridge (AndroidTV) app_id frequently shows "Failed to write while dumping service window: Broken pipe
### The problem

I have an automation (below) that triggers based on the app_Id from the device via Android Debug Bridge. Since Home Assistant 
/2023.10.4, the platform state attributes often responds with:

```
app_id: Failed to write while dumping service window: Broken pipe
app_name: Failed to write while dumping service window: Broken pipe
source: Failed to write while dumping service window: Broken pipe
adb_response: null
```

This causes automations to trigger based on the state change away from the expected values (testing for `com.valvesoftware.steamlink`).


### Additional information

A few other users have reported this via the Home Assistant integrations github - https://github.com/home-assistant/core/issues/104652
