Method 2:
I would suggest you to perform a clean boot and check if it helps.
Clean boot will check if any third party application is causing the issue, as clean boot helps in eliminating software conflicts.

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.
Hope this helps you. Please do let us know if you need further help.
