Double sneak or bounce when sneak

Sometimes when i sneak i double bounce or it double sneaks. I know this bug has already been reported and resolved but even if i go on the Minecraft version thats supposed to be fixed i still have the same problem. It happens on servers and in my private worlds. I would like if you could at least repaire the bug on 1.20.4 as its the version i always use.

 

please fix
