As sophisticated as video games become, the more complex their algorithms become. With these complex algorithms, we have begun to address new bugs. One of these errors is:

A debugger was found running on your system. Download it from memory and restart the program.


The cause of the bug is that game companies want to prevent users from debugging their source code to protect their data.

If the game suspects such a thing, it will try to block the start to protect your data.

We could try the following steps to solve the problem:

Solution 1] Windows update using Powershell

Perhaps the interfering debugger could be from a recent update. If Microsoft resolved the patch, a full Windows update would help resolve the cause. This must be done using Powershell.

1] Press Win + R to open the Run window and type the PowerShell command. Press Enter to open the Powershell window.

2] Type the following command in the Powershell window and press Enter:

wuauclt.exe /updatenow

3] Reboot the system.

Solution 2] Reset Windows updates

As the issue may be related to a recent Windows update, we may try to roll back the recent updates and see if it helps.

1] Click the Start button and then the gear symbol to open the Windows Settings window.

2] Select Updates & Security from the options and click View Update History.

3] Click Uninstall updates and in the list of recently installed updates, right click and uninstall the problematic ones.

Solution 3] Add the game to the antivirus exception list

The error occurs if the game detects that some software is trying to debug its own code. Most of the time, this is done by antivirus software to check for malware hidden in the application source code.

If so, open the antivirus application and add the game as an exception to the list of programs to scan. Reboot the system after that.

If that doesn't work, you can consider temporarily disabling your antivirus to isolate the problem.

Solution 4] Check for recently installed third party apps

If the game worked fine before and started showing issues recently, a recently installed third-party app may be interfering. We can check it and remove it.

1] Press Win + R to open the Run window and type the command control panel. Press Enter to open the control panel window.

2] Go to Programs and Features. The list of all programs installed on the system will open. Sort them in order of installation date.

3] Check if the recently installed software might be problematic. In general, freeware and lesser known software are problematic. We could try to remove them to isolate the problem. They might be installed again later.
