I'm trying to debug my project.  I'm using Visual Studio 2022 and Qt 6.4.2 Commercial.  I'd like to step into Qt library code, but cannot because

Cannot find or open the PDB file.

I've double checked what I've downloaded from Qt matches (their MD5 file agree with what I downloaded).

I inspected the dll and pdb signatures for the debug Qt Core DLL:

dumpbin.exe Qt6Cored.dll has the lines:

     Debug Directories
 
         Time Type        Size      RVA  Pointer
     -------- ------- -------- -------- --------
     6397073D cv            44 00C6B300   C69B00    Format: RSDS,

{B713CCD9-B63E-45B8-BAB2-1165E50F2E75}

, 1,
     C:\Users\qt\work\qt\qtbase\bin\Qt6Cored.pdb
     6397073D feat          14 00C6B344   C69B44    Counts: Pre-VC++ 11.00=0, C/C++=305, /GS=305, /sdl=0, guardN=50

dbh.exe Qt6Cored.pdb info gives the line:

    PdbSig70 : 0xb8de71e0, 0xe814, 0x4e1c, 0xbc, 0x37, 0xb8, 0xc1, 0x4a, 0xe8, 0x94, 0xde

After formatting both IDs, you see the mismatch:

    B713CCD9B63E45B8BAB21165E50F2E75 (dll)
    B8DE71E0E8144E1CBC37B8C14AE894DE (pdb)
