Xcode debugger can't inspect opaque C structs in a dynamic library

I have Mac OS application with several embedded frameworks. When debugging the application in recent versions of Xcode (comfirmed in 14.2) I am no longer able to inspect opaque C structs defined in a framework when the debugger has stopped in code belonging to the application or a different framework.

The application and frameworks are all compiled by me as part of the application workspace, all have debugging enabled, and all are properly generating dSYM files.

Does anyone know what might be going on? This is making debugging the framework code very difficult.
