Hi,
Please make the following changes to main.c and your Segger project to get a more verbose crash log:

Summary of changes:
1. Exclude app_error_handler(), app_error_fault_handler, and app_error_handler_bare() in main.c if DEBUG flag is set.
2. Add the app_error_handler_gcc.c and app_error.c source file to the project
3. Define "DEBUG" in the list of pre-processor symbols:
This assert indicates that the program has tried to access on of the peripherals reserved to the Softdevice (Hardware peripherals). While debugging, please read the 'info' value as the picture below shows. This will tell us which peripheral it was.
