Galaxy Book Flex α's cursor is working not well!

Hello! I am using Galaxy Book Flex α, and I loved it but unfortunately, it is not working well for the previous 2 3 weeks, it's cursor working not properly or smoothly though I have updated the cursor driver, Sometimes on the upper portion of the screen auto click occurs, I have reinstalled the windows, tested on new power plugs but it is not working. It mostly happens when I work on the following sites of my client: https://stampaprints.com/ The above sites have Nulled wp-rocket installed in them, and when I start working on it, my laptop becomes very hot and loaded, and after a few minutes cursor becomes hang and auto clicks start appearing until I restart my laptop. I don't know how to recover that, I have tried several options but no luck. could you guys tell me…
