Input delay that still not fixed

I can't play the game because of this input lag problem. It wasn't the case before 1.16 but after the release of 1.16 there is a huge amount of delay on my mouse and keyboard. They work well in Java version and other games. But Bedrock E. is unplayable. And there is no solution on the internet that solved my problem. I tried almost everything. I can't play the game.
