msvsmon.exe crashed when debugging

Question

When I debugging in VS2013 update3, msvsmon.exe crashed when hit at a breakpoint.

It shows \"The debugger\'s worker process (msvsmon.exe) unexpectedly exited. Debugging

Answer 1

I started getting this exact error today in my VS2019 project. Attempting to expand/inspect simple data structs in VS debugger would make it freeze for a minute and then I'd get that "The debugger's worker process (msvsmon.exe) unexpectedly exited. Debugging will be aborted" message:

If I add msvsmon.exe process to windows defender exclusions list, then the problem disappears.
