Debugger crashing when I hit a breakpoint

[Anonymous]

Hey all, 

I've worked on Revit previously, but the job already had the project built and so forth.  Now, I'm setting out on my own and creating a new Revit addin.  Everything is going fine but one thing, and you guessed it: The debugger crashes when I hit a breakpoint.  The builds for 2016-2018 are all good; they compile and all is right in the world, except when I want to step through the code to see what's happening.  I get this error every time:

Then, when I go to rebuild my solution, I get this:

It's not updating the DLLs because it says they're still in use.  

I've never started from scratch like this, and I've tried researching everything, but it feels like the answers are really vague or I have to run down a really deep rabbit hole that takes me to something completely unrelated before I find a solution.

What do I need to do to set up my debugger so it doesn't have a heart attack on me?

There are some settings in VS 2017 needed, like:

Enable the "Used Managed Compatibility Mode" option from Tools menu -> Options -> Debugging

Uncheck "enable just my code"

I have all that done.  After much research, I found an article on MSDN where someone who works on the debugger team essentially said, "Yea, we know that happens.  Sorry.  We're looking in to it."  I opened my solution in VS2015 and I don't have any problems.
