How To Fix Application Has Been Blocked From Accessing Graphics Hardware in Windows 10

Method 1. Set TdrDelay value

The reason this problem is occurring can be due to a few reasons, but the most likely one is that your settings are set to a slightly higher value than they should be since the application has not been fully optimized, yet. Hence, the graphics card is overwhelmed by things to load, and your application blocked from accessing graphics hardware. In order to fix this error, I would recommend you increase Timeout Detection and Recovery (TDR) delay, which in turn increases GPU processing time. To do so, follow these steps below:
Step 1. Press Windows Key + R then put regedit in Run dialog box. Click OK to open Registry Editor.
regedit
Step 2. In the left pane of Registry Editor, go to following registry location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
Step 3. In the right pane of GraphicsDrivers key, you have to create a registry DWORD named TdrDelay. To do so, right-click and select New > DWORD. Then double-click on it to change its Value data.
