Issue with v4.0.0

Hi, after recent upgrade to v4.0.0 HA v2022.7.4 (OS 8.2) which is running on raspberry 4 is no longer able to get data from the sensor.
DEBUG log has following entries:

any ideas how to fix it? cc @B1ob

I think I have the same Hardware / Software as you (HAOS as well as Airthings) and I cannot reproduce this error. First question is how far away is the Airthings Device from the RPi4 (and are the batteries full)? Because in the beginning it tries to connect multiple times to get the device info and finally succeeds the fourth time. But it fails to get the sensor data and gives up after 10 times. I am currently not at home so I cannot test how it behaves when the Airthings is (nearly) outside of the Bluetooth reach.

The distance between devices is about 20cm, it shouldn't be an issue.
