intermittent error at runtime "Unable to load function: RegQueryValueExA (ADVAPI32.dll)"

My app works fine otherwise. On some machines the error happens almost always, on others only rarely.

My target platform is Windows 10 and I get the same behavior with Windows 8.1 or either of two windows 10 SDKs.

It seems to stop if I run the app in Windows 8 compatibility mode (even when using a windows 10 SDK).

The error always happens when running the release app in the MS VS 2017 debugger, until I enabled mixed mode debugging, then I don't see the error (so far).

The app is C/C++ CLI with some windows functions. The code is not managed.

Google searching turns up nothing?

Any ideas? Seems like a compiler/linker or OS problem?

System Studio 19 latest with Intelc++, IPP and TBB. MS VS2017.

The registry reading code is from an MS example.

But it is intermittent for the same user. Sometimes it works, sometimes it doesn't, on the same PC in subsiquent runs with identical inputs.
