(My English bad sorry)

This bug has occurred in previous versions too.(ver 1.19.70 maybe). Players who join my world move faster. No resource packs and no behavior packs. I use command blocks (and structure blocks). But there's no command that makes they walk faster. About 3 months ago they was walking normally.

By the way, when they jump, their speed becomes normal. I really don't know why.

This bug has occurred in my other world too.

※ I can walk normally.

normal walk → 5 blocks/1s   fast bug walk → about 40 blocks/1s
