How to Add CONTROL Resonant to Windows Firewall Exceptions

Adding a game to Windows Firewall exceptions sounds like an online-only fix. For CONTROL Resonant, the opposite is true. Blocking the game’s network access can trigger crashes, black screens, and even the dreaded “out of video memory” error — problems that look like hardware failures but are actually firewall-related. Most players waste hours updating drivers or reinstalling before realizing a simple exception would have solved it.

Summary

This guide covers the two reliable methods to whitelist CONTROL Resonant. Apply either one, then verify the fix by launching the game.

Most players waste hours updating drivers or reinstalling before realizing a simple exception would have solved it.

Step 1: Locate the Game Executable

You’ll need the exact path to ControlResonant.execodecodecodecodecode (or whatever the primary .exe is named). On Steam, right-click the game in your library, select Manage → Browse local files. That opens the installation folder. Copy the full path or just remember the folder location. You’ll need it in the next step.

Step 2: Add an Exception via Windows Security

Press Windows Key + S, type Windows Security, and open it.
Select Firewall & network protection → Allow an app through firewall.
Click Change settings (you need administrator privileges).
If CONTROL Resonant is already listed, skip to Step 3. If not, click Allow another app.
Click Browse, navigate to the game’s .execodecodecodecodecode file (from Step 1), select it, and click Add.

Step 3: Verify Private and Public Boxes Are Checked

After adding (or selecting) CONTROL Resonant in the list, make sure both checkboxes under Private and Public are ticked. Private covers your home network; Public covers external networks like coffee shop Wi-Fi. If only Private is checked, the game can still be blocked when you connect to a different network — causing a crash mid-session.

Click OK and close Windows Security.

Step 4: Alternative Method — Control Panel (Older Interface)

If the Windows Security interface fails to save the changes (a known bug on Windows 11 23H2 and later), fall back to the classic Control Panel:

Press Windows Key + R, type control, and press Enter.
Go to System and Security → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall.
Click Change settings, then Allow another app.
Browse to the game’s .execodecodecodecodecode and add it. Ensure both Private and Public are checked.

This method bypasses the newer UI and often works when the first method doesn’t stick.

Step 5: Confirm the Exception Is Active

Launch CONTROL Resonant. If you still get crashes, repeat Steps 2–3 but also check that no third-party antivirus (Avast, Norton, Bitdefender) is blocking the game. Many of those programs override Windows Firewall — you’ll need to add the exception inside their own settings panel.

Symptom Check: When Firewall Is the Hidden Culprit

The following table pairs crashes that look like hardware failures with the actual cause — a blocked port or executable. If you see any of these, revisit the firewall exception.

Symptom	Mistaken Diagnosis	Actual Cause (Firewall)
“Out of video memory” error	GPU VRAM exhaustion	Game cannot reach authentication server, triggers a faulty memory-handling routine
Crash to desktop on startup	Corrupted game files	Firewall rejects the initial handshake; game assumes a fatal runtime error
Black screen after splash logo	Driver timeout / TDR	Game waits indefinitely for a network call that never completes

What Happens When Windows Updates Reset Firewall Rules

Windows feature updates (e.g., version 24H2) have a habit of resetting firewall rules. After a major update, test CONTROL Resonant early. If it crashes again, reapply the exception. This is especially relevant for players who already added the exception months ago — it may have been silently removed.

The fix takes less than two minutes. The alternative is another hour of driver troubleshooting.
