Roblox Memory Dump Error | Most Common Fixes

The “Memory Dump” error in Roblox is usually triggered by Hyperion (Roblox’s anti-cheat system) detecting a conflict with your Windows security settings or a background application.

As of March 2026, there are three primary ways to resolve this:

Most Common Fixes

1. The “Exploit Protection” Fix (Most Effective)

Windows has built-in security features that sometimes clash with Roblox’s anti-cheat. Turning them off specifically for Roblox often solves the crash.

1. Search for Exploit Protection in your Windows Start menu and open it.

2. Click on the Program settings tab.

3. Click + Add program to customize and choose Choose exact file path.

4. Navigate to your Roblox folder (usually %localappdata%\Roblox\Versions\version-xxx\RobloxPlayerBeta.exe).

5. Scroll down to Control Flow Guard (CFG), check “Override system settings,” and turn it Off.

6. Scroll down to Hardware-enforced Stack Protection, check “Override system settings,” and turn it Off.

7. Click Apply and restart your computer.

2. Disable “Core Isolation”

If the step above doesn’t work, a deeper Windows security feature might be the culprit.

1. Open Windows Security > Device Security.

2. Click Core isolation details.

3. Toggle Memory integrity to Off.

4. Restart your PC.

   Note: This reduces your PC’s protection against certain high-level malware, so only do this if the first method fails.

3. Clear the Roblox AppData Cache

Corrupted temporary files are a frequent cause of memory dumps.

1. Press Windows Key + R, type %localappdata%, and hit Enter.

2. Find the Roblox folder.

3. Delete the entire folder. (This won’t delete your games or account info; it just clears temporary cache files).

4. Empty your Recycle Bin and relaunch Roblox.

4. Switch to the Microsoft Store Version

If the standalone “Player” continues to crash, the Microsoft Store version uses a different architecture that often bypasses the Hyperion memory dump error entirely.

• Uninstall your current Roblox.

• Open the Microsoft Store app on Windows.

• Search for Roblox and install it from there.
