Geckolib 5.0 Entity Crashes (2023.4) (SOLVED)

Version 2023.4 (Forge 1.20.1)

Hello, I would like to know the solution as to why the game is crashing.

My custom creature worked fine before updating the workspace and geckolib version.

Any solutions would be greatly appreciated, thanks in advance.

P.S. When I spawned other animated entities, most of them worked.

PS2: I talked to the author of the plugin and he fixed it, apparently it was because of the sounds. Nerdy is a legend!
