"Index 0 out of bounds for length 0"

I transfered my 1.20.4 modpack to 1.21.4 and now, when i enter the nether, the shaders don't load and i get the message that Iris was unable to properly load the shaderpack. I have Amplified Nether, which for some strange reason doesn't work either and Not Enough Animations doesn't work either lul. My shaderpack is "Super Duper Vanilla" with a custom configuration, if someone can help me with this i would appreciate it a lot, thanks.

How have you transferred your mods?

I created a new Instance in the CurseForge App with Fabric and 1.21.4 as the selected version. Then i just started adding the mods from my list

How to find crash reports and logs
It is recommended to upload your logs to https://mclo.gs then paste the link into Discord to automatically censor potentially sensitive information and help us diagnose issues more efficiently. However, you may also drag and drop the file directly into Discord. Logs can be found in the logs folder inside your .minecraft directory. We are probably interested in the one named latest.log. Crash reports can be found in the crash-reports folder inside your .minecraft directory. We are probably interested in the most recently created one.

I don’t see the part where the shaders failed to load. It seems you also deleted the version number from super duper vanilla’s file name, so I can’t tell what version of it you are using. Make sure you are on the latest one. If you are on the latest version of SDV, try testing with only sodium and Iris

I tried disabling all the mods and leaving only iris and sodium, now the nether works. As for the shader version, i'm using the latest one, i didn't touch the shader files beyond customizing them with the in-game menu. i'll try the mods one by one to see what's causing the problem i guess

What is The Thanos Method? The Thanos Method™️ (more accurately known as a binary search) is a debugging technique used to find the mod or mods that are causing the issues you are experiencing. The method is simple: to find the conflicting mods, split your mods folder into 2 groups. Remove one group, and test in-game. Keep the group that has the problem, and repeat until no more mods can be removed without the issue disappearing. Thanks to The Thanos Method™️, you can now enjoy an issue free modded Minecraft! "The Thanos Method" is not actually trademarked or even remotely considered an official name. Please don't sue, it was just considered funny. https://cdn.discordapp.com/attachments/731716903742996531/873271100602220584/2951.1490520804.gif?ex=67042816&is=6702d696&hm=e987a97ff190ed7a7c17a3c64b5e60b05cd5ad40b1d69186d77bc7820f02cc3e&

Oooh thanks The problem seems to be the mod "Chunks fade in" which is odd

It’s known to cause issues sometimes, though I’ve never seen it cause a shader to fail to load

It can cause shaders failing to load, but only on specific ones. Haven't dive deep into why.
