mfc140.dll version 14.0.24212.0 not downloaded from microsoft symbols server

I am using Windbg to debug a dump which has mfc140.dll version 14.0.24212.0 on the main thread callstack. It fails to download this version of mfc140 for some reason.

Here is the log with sym noisy on:

I'm summarizing comments, already given answer, and my observations.

Microsoft symbol server is not able to provide some DLLs of MFC/CRT.

Yet .pdb files are there.

If an old file isn't in public pdb server, nobody could actually say what was happened. It might be a bug of build system configuration. Or a policy from these times. Or it's deleted already somehow.

For the case I just recommend updating redistributable to the latest version. MFC140.dll has the same interface for VS2015, VS2017 and VS2019.
