Here is the crash report on the server with the latest Krypton: https://pastebin.com/9iyG8BwK

Already fixed in #34

sorry if this is already a known issue.

It isn't fixed. I am using that version

This version right here: https://github.com/astei/krypton/tree/1ae22c746511246fa67d99fa970aa6d5180ca58a

Tested locally, it works fine. You probably have an old version of Krypton lurking on your server.

Nope, I just tested with that krypton right there ^ and FAPI. It gave the same error. I am using FAPI 0.36.1.

I am unable to reproduce the issue on my system, even with Fabric API 0.36.1. Check if you have multiple versions of Krypton on the system and make sure you actually have the latest version of Krypton installed.

Ok, I am still getting the crash with the latest 0.1.4 snapshot version of krypton. I tested without FAPI and the crash still happens. I made sure to turn all other servers off and delete all mods in my mods folder except for krypton. I am also running 1.17.1 now. The only differences I could think of between your test server and mine is that I am using Graalvm 16 and Windows 10.

Ok, after deleting the .fabric and .mixin.out folders, it runs smoothly. Thanks for helping me
