Broken 3D Armor Textures (MCreator 2023.4)

Hello everyone. Some days ago I updated MCreator to latest version (2023.4) and also I updated my mod from version 1.18.2 to 1.20.1. Then I met one big problem: textures of my custom 3D armor broke and now it looks like that (watch 1Picture): https://drive.google.com/drive/folders/1Iyzo0mufoyvOBtAffiy2-JnAx51AJ98m?usp=sharing
In normal case it should look like (watch 2Picture). I tried to export armor model like a new file. Also I tried to experiment with texture but it didn't helped. But it is worth noting that custom models which using by mobs looks normal.

In what includes a problem and how I can fix that?
