I can confirm I have also had this issue. I have had it on PlayStation 4 but unknown why it happens.

Do you have any resource packs or skins applied (if so which)? Molang is a math language Mojang came up with for resource packs, to help with things like animations.

We have one person using the Alex skin, another using the 'Sharkman Alon' skin from the Deep Sea Mashup skin pack and another persoon using the 'Crocodile' skin. Personally, I have not had this issue and I am using the standard Steve skin.

Just go to settings- profile- enable content log GUI and turn it off

For the past 2 weeks we have also come across the same issue.
playing on Xbox Series X and when either my partner or son join it sometimes happens. They have been using skin packs but it still happens when they change into default Steve or Alex as well.

In my situation it only happens to my friend when I am using a trident near him.

I am having this bug on Nintendo switch, 1.16.221. In my experience it happens when a player with a skin that's not Steve or Alex or a custom skin holds a crossbow.
Hey everyone, just asking when the player joins the server and the content error log appears, is the crossbow/trident/shield/spyglass in the wrong position while holding it by another player? It is most likely relates to MCPE-118539, so we wanted to make sure if that happens for others.

yes its happened with me and my freinds

That popup isn't a bug at all
That "Molang" is a thing in minecraft bedrock. MoLang is a simple expression-based language designed for fast calculation of values at run-time.
You can turn off this popup by:
For 1.17:
Goto Setting - Creator(one with command block icon)
Then turn off "Content log GUI"
For 1.16:
Go-to Setting - Profile
Scroll all the way down and turn off "Content log GUI"
That should disable the popup

I was able to reproduce this by traveling to and from the nether while another player watched while holding a trident. The trident ends up in the wrong position as described in MCPE-118539

This is while using a custom skin with a cape.

I'm still having this issue in the 1.17.11 update
Is this still an issue in the latest version of the game?
