I have a problem with C++ intellisense in Visual Studio 2019 (version 16.3.9). If I delete the .vs folder and open my solution the intellisense works correctly for a short time. After opening up a small number of .cpp source files the intellisense will stop working (this happens everytime, it always stops working). I've followed instructions from this thread:

IntelliSense broken™

but it continues to fail. I've disabled all extensions. I've turned on diagnostic logging for the intellisense and for each .cpp file that I open I can see the include paths being passed into the intellisense engine are correct yet an object defined in a header file is not recognized by intellisense. I've turned on logging of design time build (i.e. env variable TRACEDESIGNTIME is set to true) and the log file shows no Errors or Warnings for the design build.

I was hoping someone could help me understand how I can troubleshoot this issue to find out the cause.
