The animation shown on the Curseforge page doesn't work. At all. So I had to redo the entire thing with the animation maker and export it only to to be met with a freeze and "OpenGL debug message: id=1285, source=API, type=ERROR, severity=HIGH, message='Error has been generated. GL error GL_OUT_OF_MEMORY in (null): (ID: 173538523) Generic error'" being spammed in the logs after I got jumpscared from the sheer volume and took my wired headphones off (bluetooth audio doesn't work with Minecraft: Java Edition in my experience).

Well, as the error message says, you’re out of memory. Use less frames. Recommended max frames for animations are 200 at a max resolution of 1080p.

The CurseForge animation works fine btw, so you probably did something wrong or one of your other mods is breaking something.
