Camera bug ( shift animation bug )

[Trojankill]

Summary
Simple summary about the bug

Running Environment

• Minecraft Version: 1.20.1
• ParCool Version: 3.4.3.2
• Forge Version (optional): 47.4.16

Detail
I don't know what this is connected with, but I have a suspicion that Parcool mod creates a bug with the crouch animation. For some reason, from the first person, the camera freezes in a sitting position, but if you look from the third person, everything is fine (sometimes the camera can twitch). Only re-entering the world temporarily fixes this bug. ( The camera is lower than usual )

You'll find it easier to spot the error if you look at the table below. When I press the Shift key, the distance changes from 25m to 5m. This will be demonstrated in the video.

How do you reproduce the phenomenon? Which mod does show the distance in game, and what does the distance mean? Where from and where to?
Does this occur even with only ParCool without any other mods?

Well, it's quite difficult to reproduce this problem (it may appear at a random moment, but it most often occurs during a jerk, when you need to press the shift key or skills associated with holding down the shift key)
Regarding distance, this mod improves mob AI, bringing full-fledged stealth to Minecraft, similar to that found in other games. The mod makes detection at long distances easier, meaning a character in stealth mode is harder for hostile mobs to spot than in their normal state without holding down Shift (i.e., it reduces visibility and noise).
I've had this bug on my build for a long time now, the build is large with 100+ mods, but I don't think I noticed this bug without playing with the build (I also noticed another bug: when I run in Parcool mode, the screen has a chance of shaking. To fix this, I have to stop and run in Parcool mode again, even if I stop, the shaking may not stop).

If you haven't noticed in the video, the camera is lower than usual, even if I spam with compressed shift
