lag problem playing on keyboard

well it's an annoying bug that occurs in minecraft bedrock on windows 10, basically when steve is walking for a few seconds the left and right directions don't work and also in that period steve (game doll) can't jump and then he starts walking alone , it's like having a response delay on the game keyboard...

"ah but it must be a problem with the computer keyboard"

I thought that too but I tested it by playing in other games, but it doesn't happen (I even formatted my pc)
, but only in minecraft that is having this problem...
