Asset Tracker Program hangs before main on Thingy91

Hi,

We are having trouble getting the Thingy91 firmware running as is. We have achieved this in the past but I had made too many modifications and I decided to scrap it and start over. But I didn't realise that I could've just reused the cmake file so I uninstalled and reinstalled the SDK. 

We are trying to run the Asset Tracker project from the 1.3.0 toolchain.

So what happens is that when I build and debug instead of going to main() it stops here:

Then when it runs it hangs here:

I have tried to modify it to change the floating point configuration but I changed it back. I didn't try running it before the modifications

So, I figured out the problem. when I added an extra source file to the cmake file (that's how I add extra files, correct?) it was deleting the main.c file and this was because I neglected to add a proper CMakeLists.txt file to the directory. So now it works but I have 2 questions.

1. First we think that perhaps running from the code has a different sampling frequency from the other version he ran (out of the box). IS this possible?
2. When he was collecting data he was able to obtain the air_quality value but for me that code is absent. Is it possible to obtain this segment or get help on how to fix it?
   env_sensors.c
   int env_sensors_get_air_quality(env_sensor_data_t *sensor_data)
   {
   return -1;
   }
   
   this code is called from env_data_send(void) in main.c
