No module information in minidump on win 11.

Question

There are problems with my application on win 11.

For some reason, when running win10 version of my application, there is no needed information in the minidump crash file. Using the minidump_dump tool I figured out, that there are no debug_id and pdb_file information for the main module in the minidump file. Strange thing is that after running win32 version or running the application from Visual Studio, and successfully crashing (for this versions crashes have needed information), crashes from win10 version become having needed information. And this keeps until restarting of computer.

We use dbghelp.dll library, the following way (that's not the whole code, only main actions):

dbgLibrary = LoadLibraryW(L"dbghelp.dll");
LPMINIDUMPWRITEDUMP pfnMiniDumpWriteDump =
                (LPMINIDUMPWRITEDUMP)GetProcAddress(dbgLibrary, "MiniDumpWriteDump");
pfnMiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), file, MiniDumpNormal,
                &exceptionInformation, NULL, &callbackInformation);

We don't have any platform-specific code in this part (for win10 and win11 this code is the same), but for some reason on win11 this code does not work as expected. I will be glad of any information and ideas on why this could happen. The only difference between win10 and win11 is versions of dbghelp.dll, but the code of this library is not open, so I cannot figure out why this could happen. Also this happen only on uap version of our application.

Here minidump_dump analysis for crashes with and without needed information:
