LIghtroom Classic: Slow editing/scrolling

Hi, 

Right after install, I am having issues with extremely slow editing, scrolling through photos, adding or applying changes to images.

The laptop was new and had 16 GB but now it is upgraded to:

Device name DESKTOP-C69QGDA
Processor Intel(R) Core(TM) i7-10875H CPU @ 2.30GHz   2.30 GHz
Installed RAM 64.0 GB (63.9 GB usable)
Device ID 455D2FFB-86F5-4D5D-9408-D46ACF0BF1E9
Product ID 00325-81810-72643-AAOEM
System type 64-bit operating system, x64-based processor

I can no understand what is causing the problem and making the lightroom almost unusable?

Can you look into issue please, if this is not improved i will ask for refund as free software does 10x faster job in editing pictures from my SONY a7ii which is pretty old and images are tiny in size.

Thanks
