Solutions

1. Open Help | Show Log and inspect the stack trace for the underlying cause.
2. Retry the action after restarting the debug session; report the issue with the log if it persists.

Example fix

Help | Show Log in Explorer -> idea.log -> search for the timestamp of the failure.

When it happens

Trigger: An unexpected internal exception occurs while resolving a field descriptor in the debugger.

Common situations: Rare debugger/JDI inconsistencies; the log contains the real exception.
