I updated my Visual Studio installation, and now UBT succeeds in building the game C++ sources but the engine fails to load the built modules. Building from editor just reports “module failed to build,” but running from UAT shows the real error is that the engine fails to load the module.
With a clean new blank C++ project with just the Config, Content, and Source directories present:

This is a log trace with UE 4.27.2 configured to use Visual Studio Community 2019 Version 16.11.20, but I also get the same result from VS Community 2022 Version 17.3.6. (Unfortunately, I don’t know the last version that worked.)
UE 5.0.3 with VS Community 2022 Version 17.3.6 successfully builds and loads the module’s content.
Does anyone have a workaround or am I just going to have to install and hope that the VS 17.0 and/or 17.2 LTS don’t break UE? (I only have access to mainstream VS support, so my options are 16.9.X (EOL 2022-10-11, this previous Tuesday), 16.11.X (broken), 17.0.X (untested), 17.2.X, (untested), or 17.3.X (broken).)
I have access and experience with engine source, but my team is using the retail engine (and pinned to 4.27.2 for this project), so a custom engine patch is unfortunately not an option for me.
I’m the one on the team pushing people to update their tools more often than the “industry standard” of “roughly never” and I guess finally ate my comeuppance this time.
