Windows 10 Start Menu not working

Hello all, last night I Update my windows 10 pro after the update is complete I restart my PC when the booting process is complete, and system boots up, I pressed the windows key and relies on that it isn’t working, firstly I think this may be the windows error, I restart my PC again and again but the problem is same as previous. so can anyone help me to fix this issue or this may be Keyboard/Windows Error? Waiting for Your Help and Suggestions!
Thank You.
