When I play Minecraft for a long time, after a while there's a hacking game?

If I play minecraft for about half an hour, a little chop comes after a while you know what I mean? When I reinstalled minecraft, it didn't go away? Then what can you do?

Java or Bedrock?

Java

I don't know anything about Java because I play Bedrock, but sometimes it is the same with me and my sister. She thinks it's some kind of bug. For us it helps to close the game and reopen it, but unfortunately I can't tell you more because I have no idea about Java.
