ERROR_INVALID_EXCEPTION_HANDLER
An invalid exception handler was detected
ERROR_INVALID_EXCEPTION_HANDLER signals that the exception-dispatch or unwind machinery encountered a handler that is not valid for the current process state. Memory corruption, a damaged stack, or incompatible low-level instrumentation can produce this result.
Investigation
- Capture a crash dump at the first occurrence.
- Enable compiler and runtime protections such as stack checks where available.
- Review injected modules, hooks, profilers, and handwritten assembly.
- Check earlier memory-access violations rather than treating this as the original defect.
Handling
Do not continue execution after the runtime reports a corrupted exception chain. Fix the component that damaged control-flow or unwind metadata.
