I was able to find the error log. It seems related to the serial wire viewer I am using to print Hello World. I will appreciate if anyone can help explain the problem and suggest any solutions. 

I get a similar error when I try to debug. the disassembly is empty but if you launch the window again you can see the assembly code. The assembly code isn't highlighted green along with the c code. It used to track earlier.Any ideas how to get this ...
