Why does this cause an exception when I open a CDatabase (ACCDB)

Question

Sample project:

https://www.dropbox.com/s/ezwe48gpezrr19u/MFCApplicationDB.zip?dl=0

I am using VS 2022. Has basic code in the dialogs OnInitDialog:

CDatabase db;

if (db.OpenEx(_T("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=D:\\Test.ACCDB;Pwd="), CDatabase::noOdbcDialog))
{
    AfxMessageBox(_T("DB Opened"));
    db.Close();
}

When I run this in DEBUG and simply start it, it opens the DB and then I shut down the application I get an exception:

I am building x64.

FYI:

My PC is:

• Windows 11
• Microsoft 365 64 bit

In the comments it was suggested to load symbols, but I don't have Mso20Win32Client.pdb.

If I trace into clicking the Ok button to shutdown it eventually gets to this closing } in system code:

#pragma warning(suppress: 4985)
{
    // call shared/exported WinMain
    return AfxWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
}

Went it hits that it crashes.
