Hello Nidhi.

This looks like a simple case that symbols are not loaded for the module in
question. That would cause all the breakpoints within that module to go
unresolved. This is also backed up by the error message you are seeing.
Have you examined the debugger help on "symbols"? It contains a lot of
information on how to triage symbol problems.
