Latest ODBC Driver 18 for SQL (18.7.1.1) breaks SCCM Site Server > SQL connectivity

It looks like SCCM is trying to maintain an updated runtime. I can find in:

C:\Program Files\Microsoft Configuration Manager\bin\X64

a fairly recent vcredist_x64.exe and an attempted install log (vcredist.log) in the same path (dated a week ago, around a hotfix install).

The runtime in the folder is version 14.50.35719, while the system already was at 14.51.36247.0.

Seems like SCCM wants to stay update to date on the runtime, just it has some old runtime files (seeing 2021 files, v14.28) in its bin folder.
