Research direction
Start with com.microsoft.java.debug.plugin/src/main/java/com/microsoft/java/debug/plugin/internal/ResolveMainClassHandler.java at line 156, then reproduce the failure from the Java Projects tab or Spring Boot dashboard using the reported environment. Trace why LookupEnvironment.getType returns no types after the 1.26.0 update, and verify that a project main class is detected and can be launched or debugged.
