What's the issue you encountered?

I hate to bring 1.20.4 into this 1.21+ but I have been looking for answers all over and no one is wanting to help me. It's been hours.

I was playing my modded server, turned on shaders, used a waystone and boom. I can no longer join my server and am greeted with an error

This error will not go away, I don't crash at all. It just gives me this error. I hard reinstalled everything. I'm using Feather Client (Fabric api 1.20.4 etc.) and everything was perfectly fine till I used a waystone.

How can the issue be reproduced?

You would need my entire mod pack, turn on shaders. And use a waystone(?)

Additional information

I'm just desperate, as It's sad that I can't play my own server. It's been hours. I'm not a coder or anything, so bare with me with this I have no clue what to be doing.

I figured something out, if you are active please reach out on discord (I left a message in general.) and I need help figuring something out

If you encounter this issue, update your mods in your server/client
