Describe the bug
When I run this mod with or without other mods it freezes on the loading screen. I attempted to install the mod on my Windows 10 PC and it worked fine. I noticed that my Windows 10 Minecraft game screen resizes near where my MacOS freezes, so maybe that can be an issue? Also, the game freezes with or without animations installed.

To Reproduce
Steps to reproduce the behavior:

1. Installed the mod
2. No crash but game freezes.

Crash Log
No crash log, here is what I get in the logs:

I can Discord/screen share if needed. I was looking into the source code to see if I can spot the issue but I ran into other issues with unknown function names. I plan to use this mod to make some sweet modpacks/youtube video series. Thanks

Yeah, there seems to be some problems with FancyMenu on macOS.. I will try to add better compatibility for macOS with the next update! :)

Fixed with FancyMenu v1.2.1! Thank you for your report! :)
