~1 Second lag when pressing WASD

This has been happening for a while on Minecraft Bedrock Edition (on Java it works fine). So there's about a 1 second delay every time I press WASD to move in a certain direction, but it basically makes the game unplayable. I tried looking it up to fix it but the solutions haven't worked. I've seen that it happens with a lot of other people, but no solution has worked.
