The ERROR_DBG_CONTROL_C Win32 system error, with code 693 (0x2B5), indicates issues with the debugger or the debugging process. The message for Error Code 693 reads, Debugger got control C.

The system code usually appears due to corrupted system files, outdated drivers, conflicting applications, and a buggy or incompatible BIOS.

If a quick app removal didn’t work, there may be leftover files or Registry entries still conflicting with Windows. So, I recommend using a top-rated software uninstaller to wipe all traces of the app installation.

  2. Click the System Restore button.system restore to fix ERROR_DBG_CONTROL_C

For a few, a bug in the installed BIOS version was responsible for ERROR_DBG_CONTROL_C. So, if a new version is available, update the BIOS. Otherwise, downgrade to an older BIOS version.

Since the BIOS update is tricky and different for each computer, I recommend you check the manufacturer’s official website for the exact steps.

One of these solutions should have ideally fixed Error Code 693 (Debugger got control C). If not, the last option is to reinstall Windows. It will certainly get things running because the problem is almost always caused by software-based issues.
