BLE Radio Fault

Question

Hello, 
 
 we recently received our new custom PCBAs with nRF52833. this is the 2nd rev of our design and the first design functioned as expected. with this new board, I am able to program the device and run simple print hello world. when I loaded our developed FW where one of the first things we do is advertise, the app crashes with the following output:

and after running the addr2line, I get the following

the app seems to crash without much info as to what is causing it. I have a feeling it has something to do with the 32MHz crystal but this is the same crystal as our original design with the same load capacitance. one of the major differences with the new board design is we added the external 32kHz crystal but I have not even configured to use it. any help as to what may be causing this issue would be greatly appreciated. 
 
 here is the code
