Not sure why it's happening i just downloaded sodium 1.16.3 fabric mod and added it to my fabric mod folder and started the game and it won't load up it says:

The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'client' due to errors, provided by 'imm_ptl_core'!
Exit Code: -1

Kind regards

Unfortunately Sodium and Immersive Portals are both incompatible with each other due to how rendering works. You'll have to make a choice of which one you'd like to keep.

You can use qouteall/sodium-fabric, it's a fork by the creator of Immersive Portals. Just keep in mind if you run into any issues. You should open an issue at quoteall's repository not the official one.

Closing as a duplicate of #15. You’ll either need to use an unofficial fork, or wait for compatibility.
