If you're getting the "Roblox Encountered an Unexpected Error" warning message, you're far from being the only one. Roblox players have been reporting this issue en masse over the last couple of months, with the pop-up window prompting you to click OK in order to create and capture a Roblox memory dump. What does this mean, and how to fix it? Here's what we know.
How to Fix Roblox Encountered an Unexpected Error Issue
The issue usually appears when Roblox has trouble interacting properly with your PC, either with Windows or certain parts of your hardware. Players have been sporadically reporting this bug for several months now, usually rendering them completely unable to even start Roblox, let alone play any games on the platform.
The good news is that the developers are well aware of the issue and are working on implementing patches to fix it. In the meantime, on the official Roblox forums, some members of the Roblox staff have suggested several possible workarounds that may resolve the problem before a patch is released. The possible solutions for the “Roblox Encountered an Unexpected Error” issue below were shared by a Roblox developer.
Uninstall and Reinstall Roblox
The first potential solution is the easiest and safest option. You should completely uninstall Roblox, restart your PC, and then reinstall the platform. While not a 100% guaranteed solution, a number of players have reported that this did the trick for them and that they are no longer prompted to create a Roblox Memory Dump.
WARNING: The next few solutions, despite being offered by an official Roblox developer, may be risky for the health of your PC and are not recommended unless you are confident in what you’re doing. Do not try them if you are not prepared to accept certain risks.
Test Third-Party Antivirus Programs
If you are running third-party antivirus programs (other than Windows Defender), a Roblox developer recommends temporarily disabling them to determine whether they are causing the “Roblox Encountered an Unexpected Error” message. Perform this test only if you’re confident that Windows Defender is doing a good job protecting your PC and that you don’t need an extra layer of security.
If you suspect there is a potential threat to your PC, do not disable your third-party antivirus software. On an additional note, a number of players have reported that the issue is specifically related to the Norton 360 antivirus app, so if you’re using it as well, it might be worth trying to uninstall it and see if that fixes the problem.
Turn Off Secure Virtual Machine (SVM)
This falls under advanced troubleshooting, but it may be worth a try, as many people have confirmed that it resolved the issue for them. Again, do this only if you’re confident in what you’re doing and are aware of the potential consequences. In most cases, unless you are using your PC to create virtual machines, emulators, or other similar apps, you likely don’t need this feature. Here’s how to turn it off.
- Restart your PC
- When the PC starts to turn back on, press the Delete key several times until you enter the BIOS.
- Check your motherboard manual to find where in your BIOS the option to disable SVM is located.
- If you have an AMD processor, it’s usually found under the “Advanced” or “Configuration” tab, then “CPU Configuration,” and finally the “SVM Mode” setting.
- Once you're done, save BIOS changes and restart the PC.
NOTE: Many players who experience this issue report having an AMD processor, so the issue may be related to AMD.

Turn Off Memory Integrity
Memory Integrity is one of the newer Windows features designed to protect your PC at a core (kernel) level. While it plays a critical role in system security, it has also been reported to significantly hamper game performance and even prevent some games from working altogether.
Disabling it may leave your PC more vulnerable, but for the vast majority of users, this is unlikely to be an issue, as it is primarily related to more advanced attacks that do not affect everyday internet usage. Here's how to do it:
WARNING: Despite being officially suggested by some Roblox developers and despite working as a solution for many players, it is generally recommended not to turn it off. While it may not cause issues for most users, it does expose your system to unnecessary risks. Proceed at your own risk.
- From the Desktop, search Windows Security and open it.
- Click on Device Security.
- Select Core Isolation and turn it off.
- Restart your PC.
