Description
The problem
After updating to core-2021.7.0 my ESP32 camera feed stopped displaying in my lovelace view.
Looking into the HA logbook, I found the camera entity was continually toggling between available and unavailable.
This ESP32 camera module is running firmware compiled with ESPHome (1.19.4).
The ESP32 board in question also has a a few sensors connected to its GPIO pins as well as some very generic ESPHome sensors (uptime, wifi signal, reboot switch, etc).
I notice that every time HA tries to poll the ESP32 for an image, the HA API disconnects from the device (which causes all the other sensors/switches/entities associated with the ESP32 to briefly toggle offline too).
If I remove the esp32_camera component from the firmware, the HA API remains connected and the entity state of my sensors/switches remains online as expected.
Rolling back to HA 2021.6.6 fixes the issue - the camera feed works and the HA API remains connected with no problem.

Every 10 seconds when HA polls the ESP32 for an image, the ESP32 logs the following:
[14:26:05][D][esp32_camera:156]: Got Image: len=38209
[14:26:05][D][api:067]: Disconnecting Home Assistant 2021.7.0 (192.168.6.8)

... and any entities associated with the ESP32 toggle offline in the logbook:
espcam_1 Restart turned off

espcam_1 Restart became unavailableAdditional information
- Rolling back to HA 2021.6.6 resolves the issue
- Commenting out the esp32_camera settings (which obviously stops HA from polling the camera) also makes the HA API stabilise and the remaining sensors/switches work fine.
