Laptop Display flickering at 144 hz but stable at 60 hz and BIOS Screen.

[PolluxBloom]

I have been using my HP Pavilion Gaming - 15-ec1052ax gaming laptop for half a year now. I use my laptop everyday extensively for work, multimedia and gaming. Everything was buttery smooth up until the past two days where I see my display flickering and freezing especially with mouse clicks and movements. Also i see bunch of horizontal line flickering at the top of my screen. Also some icons in my taskbar and desktop turn into black squares.  

The issue started after the Windows 21H1 update on 18th May. 

Magically, when I turn down the refresh rate of my display to 60Hz from 144 Hz, the flickering kind of stops.

But I guess there is no point in using 60hz refresh rate when I paid more for a 144hz display. hope you all agree that.  

I have tried uninstalling and re-installing the graphics driver, did not help.

I also tried resetting my PC , that also did not help. 
I am sure there no Incompatible app that is causing this issue, because the issue persisted after I reset my PC and removed everything. 

I doubt if this is a hardware issue because the display runs fine on BIOS and also in 60Hz.

I am really feeling helpless now and looking forward to this community to show me a way to get it fixed. 

I beg for your help!!!!!!!!!!!
