A very especific error with maxEntityCollisions

[PenOfEnder]

Sorry for my bad english i'm using google translate and my basic english knowlegde

Hi, I'm upgrading my world from version 1.21.1 to 1.21.4, and I started getting an error (image attached) and searching in forums it turned out to be a mod, this being the carpet mod. Once with this, I asked myself "is it the mod or the world?" so I decided to enter another empty world and it didn't give me the error, so I decided to delete my carpet.conf and I was able to enter without the error, I deleted properties and the one that turned out to give the error would be maxEntityCollisions

Once I detected the property causing the error, I deleted it and it allowed me to enter the world.

It should be added that if you try to manipulate the property with /carpet in the world it crashes.

EDIT

I attach an image of the file comparison, since the one that does not have the active property allows me to enter the world
