Hi Mirza,
Thank you for posting your query on Microsoft Community.
As per the description, I understand that you are facing some issues with Windows.
This issue might have occurred due to some third party application conflicts.
Let’s try the following methods and check if it helps:
Method 1:
Step 1:
I suggest you to try to boot the computer in safe mode and check, Please refer to the below Microsoft article and check if it helps.

Step 2:
I suggest you to perform clean boot and check, using this Microsoft Article because may be a third party application is causing this issue.

NOTE:
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.
Method 2:
I would suggest you to perform a SFC Scan and check if it helps.
Refer to the following link given below.

Note: While performing SFC Scan I would recommend you to make sure that there are no applications or programs running on the back ground.
Method 3:
I would suggest you to temporarily disable the antivirus security software program installed on your computer and check if that helps.
Disclaimer: Antivirus software helps protecting 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 and\or troubleshoot any pertinent issue, you should re-enable it as soon as you're done. If you are connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to malware attacks.
Hope this information helps. Please let us know if you need any other assistance with Windows in future. We will be happy to assist you.
