application exception

0x80000004 SINGLE_STEP

A single-step debug exception escaped without a debugger — unusual for end users; sometimes left behind by anti-cheat or instrumentation. Update those components first.

What to do about it

  1. Update anti-cheat / game overlay components.
  2. Update the program.
  3. Reboot after uninstalling invasive monitoring tools.

Where you will see this

Windows Error Reporting writes this code into Report.wer files and app-crash minidumps when a program dies but Windows itself stays up. It is not a blue-screen stop code — for those see the stop-code library.

See which module threw this exception

Drop the program's .wer report or crash dump into the app-crash reader — the faulting module is usually the real story. Parsed locally.
