LPC11C24 ResetISR() error

[f_fiorini]

Hello,
I'm developing an application using Deep Sleep mode with the LPC11C24 board.
As our setup we are using the LPCXpresso LPC-Link LPC11C24 Rev B board and MCUXpresso 10.2.

I just tried to work on the code for the deep sleep mode and I got this error message from the debugger:

15: Target error from Set break/watch: Et:96: Pseudo-address (0xFFFFFFxx) for EXC_RETURN is invalid (GDB error?)
Debugging context: bms LinkServer Debug

The error persists even after attempting an ISP Reset, which usually cleared all possible errors derived from misconfiguring Deep Sleep mode. 

Furthermore, it seems from the IDE that the execution stops at ResetISR() but I haven't called it in my code, so perhaps  is a board's problem.

Any suggestions on how to continue? Or how to solve this problem? 

EDIT: 
This is the full console output for the debug session:
