Solutions

1. Verify the JDK used to launch the debuggee is intact; reinstall or re-register it if files are missing.
2. Point the run configuration to a valid JDK under File | Project Structure | SDKs.

Example fix

Re-add the JDK home in Project Structure | SDKs, then retry the debug session.

When it happens

Trigger: The debugger fails to initialize because the target or helper JDK installation is broken or incomplete.

Common situations: A partially deleted JDK, a JRE used where a JDK is required, or a JDK home path that no longer exists.
