I'm developing application based on asset tracker, which should use BME680 AQI library and sensor. Everything was working as expected until I once left sensor for about 2h to gather data and it apparently got hanged (data stopped flowing to nRF cloud, even with Pro plan). I tried to flash again SiP firmware (we are using 1.3.3) and clean Asset Tracker app from SDK v2.1.1 - no action, LEDs are off (even with UI module enabled), no data is flowing.
I managed to gather some logs via LTE Monitor and I can see some errors right after switching on the device:

From what I found on other post, Error on I2C line occurred for message 0, indicates some issues with I2C addressing, but I haven't changed anything on a board - is it possible it's a software issue or does it indicate hardware problem? Should I perform some additional troubleshooting?
