Hanging Of Mouse & Keyboard & Fedora 34 PC

Hello Fedora Community,
I have using Fedora after knowing Privacy Nightmare of Windows & fallen in love to this OS. But after upgrading to Fedora 34, 1month back I am encountering problem in Mouse, Keyboard & Subsequently in PC.
Firstly the Mouse is in the mode of “Continuous Left Click” & simultaneously Keyboard also not responding to most of the keystrokes & then a little bit later the “Screen Become Standstill Till Manual Restart Happens”.

I am using Intel NUC with Celeron J4005 2.7GHz, 4GB DDR4 RAM

Please help.
