`.\build.cmd -subset clr+libs -config release` fails in `ConfigurationBindingGenerator`

As per the title, currently running .\build.cmd -subset clr+libs -config release currently fails with the following:

Can you check again with the latest bits? Doesn't repro for me with latest main e264ba7. What commit were you folks on when you saw this?

[jasper-d]

Does repro for me with 218d2ef and git clean -ffdx && dotnet nuget locals all --clear && .\build.cmd -s clr+libs -c Release. Will try with e264ba7 next.

Still able to reproduce with e264ba7. This is what I ran:

git checkout e264ba7
get-process dotnet | stop-process
dotnet build-server shutdown
git clean -ffdx
dotnet nuget locals all --clear
.\build.cmd -s clr+libs -c Release

[tannergooding]

Same. I'm also able to repro still using 5a43a6f

I've hit a couple of errors trying to build with the preview 6 SDK installed.

Do y'all have .NET 8 preview 6 installed? Does it build if you do export useInstalledDotNetCli=0 then try a build?

I get this on debug builds as well, but in that scenario it will trigger an assert instead of a crash. I have currently not found a way around this issue.
