Solutions

1. Do a clean rebuild to regenerate class files with valid debug information.
2. Restart the debug session afterwards.

Example fix

Build | Rebuild Project; then start the debug session again.

When it happens

Trigger: Stack frame debug data (variable slots, line tables) is unreadable or inconsistent.

Common situations: Bytecode transformers, obfuscators, or partially recompiled classes producing corrupt LocalVariableTable entries.
