Sometimes when I run close to a tree or a 1 block gap space and sneak (shift) I enter the crawling animation (swimming) but if I get out of the space it comes back to normal. It happens randomly and it's a weird bug or maybe glitch.
Environment
Java version 8 update 251 (build 1.8.0_251-b08), windows 10, mid-spec pc.
