Game crashing after porting mod to MCreator 2025.2

I wanted to port my mod from MCreator version 2024.4 to this one, I had Nerdy's GeckoLib installed so I removed all entities and disabled the plugin, It ported fine and the game launched, but when I clicked Create New World the game instantly crashed. I tried removing elements to the point where the workspace was empty, but it still crashed. Here is the crash report : https://drive.google.com/file/d/1rbjYw03Y_F3c2wo6VkkspYst7Cx2wX9I/view?usp=sharing

I understand that names with uppercase letters are not allowed, but why did the game work in MCreator version 2024.4 ?

I fixed some of the errors, but it still crashes: https://drive.google.com/file/d/1LDtwOsV2l_Lt1v9bUkV9wmy-tpUY6USL/view?…
