Method 2: I suggest you to temporarily disable the antivirus and check if it helps.
Disable Anti Virus:
NOTE: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus
software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
If you the issue still persist, refer to the below method.
Method 3: I would suggest you boot the Computer in clean boot mode and troubleshoot with the issue.
Refer to the below link to enter into clean boot state. The below link can also be applicable to Windows 10.
Clean boot disclaimer: A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists. If the computer is connected to a network, network policy settings may prevent you from following these steps.

Once you perform clean boot do refer to the section “How to reset the computer to start normally after clean boot troubleshooting” to boot the computer in normal mode.
If you the issue still persist, refer to the below method.
Method 4: If you are still unable to upgrade to Windows 10. Then I suggest you to try to use the create Media installation tool in the below Microsoft Help Article and try upgrading to Windows 10. Chose the option as Upgrade from the Media creation tool.
Before upgrading to Windows 10, I suggest you take a backup of important files and folders on external hard disk.
