Breakpoints not working in simple Angular 7 app

I've read through a dozen posts on this issue and none of the suggestions work.  The problem is simple: I set a breakpoint (no "check" appears in the red circle) and start the debugger and it does not break at the breakpoint.  I can provide the entire project if necessary.  This is a showstopper for me to consider purchasing WebStorm.  Solution?
