Title. We just got elytras on our server and cannot use them because of this crash.

And yes I did try disabling the enchantment in the config, it did not fix the bug.

Hi, thank you for reporting!
I will further look into this.

You are using NeoForge 21.1.90 for 1.21.1, correct?

Yes, that is the case.

This has just been fixed on Accessories' Curios Wrapper's end.

Sorry for the long silence from my side. Studies caught up to me.
I'll mark this as closed for now, since @DarthCaesium mentioned it has been fixed.
If the issue comes up again, feel free to reopen!
