Run a System File Checker Scan
The Application has been blocked error can be due to corrupted graphics card system files. So the System File Checker , which scans for and repairs corrupted system files, can potentially resolve the issue. This is how users can run an SFC scan within Windows 10. Open the Win + X menu with the Windows key + X keyboard shortcut. Click Command Prompt (Admin) to open the Prompt’s window. Input ‘DISM.exe /Online /Cleanup-image /Restorehealth’ within the Command Prompt, and press the Enter key. Thereafter, enter sfc /scannow and press Return to initiate an SFC scan that might last for about 20-30 minutes. Restart Windows if the system file scan fixes files.
