Applications such as Bitdefender also have a Gaming Mode feature that ensures that your antivirus doesn’t interfere with your gaming sessions in any way. If you’re looking for an antivirus that will protect your PC without interfering with games and other software, you should definitely consider Bitdefender.
Solution 4 – Solution Turn off Controlled folder access
According to users, sometimes certain features can cause Windows Defender to close games. This antivirus has a useful feature called Controlled folder access, and thanks to this feature it protects certain folders from third-party applications.
Unfortunately, this means that this feature can sometimes prevent your games from making changes in certain directories. As a result, the game might not be able to start at all. However, you can fix this problem simply by turning off Controlled folder access feature. To do that, just follow these steps:

Solution 5 – Turn off Real-time protection
Windows Defender scans your computer in real-time, and if it notices anything suspicious it will block it from running or give you a notification. Sometimes Windows Defender can interfere with certain software, and that can lead to various issues. However, you can circumvent this issue simply by disabling real-time protection.
To do that, just follow these steps:
- Navigate to Windows Defender Security Center.
- Go to the Virus & threat protection and then choose Virus & threat protection settings.
- Locate Real-time protection option and disable it.
Once you disable real-time protection, your games should start working again without any issues. Keep in mind that disabling this option will make your system more vulnerable, so use this workaround only during the gameplay sessions.
Once you’re done with the game, be sure to turn on Real-time protection once again.
Solution 6 – Make sure that the file you’re trying to run isn’t blocked

- Now you should see the Unblock option at the bottom of the Properties window. Check the Unblock option and click Apply and OK to save changes.
After doing that, the application should be able to run without any problems.

If any updates are available, they will be downloaded automatically in the background. Once the updates are downloaded, you’ll install them automatically as soon as your system restarts. Once everything is up to date, check if the problem is still there.
Solution 9 – Perform an in-place upgrade
