Hi,
Certain things you can try are to find out the root cause of the problem are given below.
1. Have
a look whether you can reproduce the problem in safe mode.
Start your computer in safe mode

If behavior doesn’t persist in safe mode, it indicates that a third party program or service is preventing you from performing
the action as supposed to.
To validate or determine which service/startup item could be causing this, restart the computer and boot to desktop normally. Once
done, perform clean boot.
2. Clean
Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior.
Refer:

Note:
Ensure that you put your computer back to normal startup mode after completing the troubleshooting steps. Steps are available in the article given above.
