Alternatively, you can use a VPN to bypass restrictions imposed by your ISP and launch the game again to check if the error has been fixed.
Disable DEP feature for Windows
Data Execution Prevention is a Windows security feature that helps to shield Windows systems from threats like viruses and the likes. While this is a useful Windows feature, it has also been proven to be likely responsible for glitches in the MTG Arena game which may give rise to the “GetThreadContext Failed” error. What you can do is to exclude your MTG Arena from the DEP service or disable the feature.
Note however that this fix comes with the risk of making your Windows system vulnerable to threats like viruses and the likes.
- Close the MTG Arena application and end all processes related to it in the task manager.
- Launch the Control Panel, navigate to and select “System”.
- In the System window, select “Advanced system settings”.
- In the Advanced tab, click on “Settings” under the “Performance” section. This opens the “Performance Options” window.
- Navigate to the Data Execution Prevention tab and select the “Turn on DEP for all programs and services except those I select” option.
- Proceed to exclude MTG Arena from the list.
With that done, you can launch the MTG Arena game again to check if the error has been fixed. If the “GetThreadContext Failed” error persists, then you should go on to completely disable the DEP feature. Follow the steps below to disable the DEP feature for Windows.
- Press the Windows key + X on your keyboard and from the options that pop up, select Command Prompt (Admin) or Windows Powershell (Admin) as the case may be.
- In the command prompt window, type in the command:
bcdedit.exe /set {current} nx AlwaysOff and press Enter.
- Restart your computer and launch the MTG Arena game to see if the issue has been resolved.
If you need to enable the DEP feature again, just follow the same steps and replace “AlwaysOff” with “AlwaysOn” in command prompt.
Change the Antivirus and Firewall settings
This is another fix you’ll be trying at the expense of exposing your personal computer to the risk of damage by threats such as viruses, trojans and the likes. Changing your Antivirus settings as well as those for Windows Firewall can sometimes be the fix for the “GetThreadContext Failed” error in MTG Arena, so you might want to take that risk.
- You can start by disabling your Antivirus and Firewall. Check to see if any of MTG Arena’s related files are in your antivirus//firewall’s quarantine settings. If that is the case, restore those files to their original locations.
- Launch MTG Arena and check if the “GetThreadContext Failed” error has been fixed.
- You can also choose to add the game and its entire installation folder to your Antivirus/Firewall’s exception list.
- Launch MTG Arena and check if the “GetThreadContext Failed” error has been fixed.
- If the adjustments to your Antivirus/Firewall above still do not fix the issue, you can make these custom changes that have been proven to work by many MTG Arena players to help solve the “GetThreadContext Failed” error.
- For Avast users: Open the Settings menu and locate “Troubleshooting”. In the “Troubleshooting” options, uncheck the option to “Enable hardware-assisted virtualization”. Restart your computer and launch MTG Arena once again to check if the issue has been resolved.
- For Kaspersky users: Navigate to “Application activity” in the app and add all of MTG Arena related processes and Unity to “Trusted”. Restart your computer and launch MTG Arena once again to check if the issue has been resolved.
- For all other Antivirus applications, all you simply need to do is revert the antivirus settings to default, and then restart your computer and launch MTG Arena once again to check if the issue has been resolved.
Restart Update Downloads
Last but not least on the list, you can simply restart the downloads of updates for MTG Arena as the “GetThreadContext Failed” error can sometimes be caused by some temporary glitch in the communication/application modules of the game.
Close the game and if you’re unable to do that normally, don’t be afraid to force-shut the game by pressing Alt+F4. Then launch the game and start the download, it is expected to continue from where you left off.
If the download freezes again with the “GetThreadContext Failed” error persisting, close the game and repeat the process for a few more times until the problem is solved. Some users claim that this method proved helpful on their 10th trial or thereabouts, so don’t give up too soon.
Hopefully, one of the fixes discussed in this post has been able to help you solve the “GetThreadContext Failed” error in Magic: The Gathering Arena. Feel free to share with other users, which of the above-listed methods helped you.
