No database created during queryCompilerDefaults causing cpptools to exit

I am getting this crash with the release and beta versions, and I would love to help you track this down because intellisense has always been hit or miss for me for (literally) decades!

I have attached to the 'ms-vscode.cpptools-1.22.11-win32-x64\bin\cpptools.exe' process, but it just eventually exits with exit code 0, so I can't get a stack trace from that.
Could you advise what I should attach to, and if there is a version of it with symbols?

This is the log from the Output window:

Start with the cpptools/queryCompilerDefaults request in the provided Output log and reproduce the exit using cpptools.exe 1.22.11 on Windows. The report names no source file or test, so first identify the native process and obtain symbols or a trace. Done means the exit cause is isolated and the query no longer causes cpptools to terminate unexpectedly.
