Hello,
Thank you for replying.
A quick question before we proceed:
Is this issue confined to a game?
I suggest you to do a clean boot and check if any third party apps are causing the issue.
Placing the computer in a clean boot state can reduce software conflicts and help identify the root cause of the issue.
Please refer to the article below for steps to perform a clean boot.
