Attempted to retrieve active rendering plug-in before one was registered

What the log looks like

java\.lang\.UnsupportedOperationException: Attempted to retrieve active rendering plug-in before one was registered\.
net\.fabricmc\.fabric\.impl\.(?:client\.)?renderer\.RendererManager\.getRenderer

How to fix it

1. Update Sodium and Iris Shaders to their latest releases for your Minecraft version, as newer builds add support for recent Fabric API changes.
2. If Sodium and Iris are already on their latest versions, downgrade Fabric API to the previous stable release (avoiding beta builds) until Sodium updates.
3. If you are on an older Minecraft version where Sodium did not include built-in FRAPI support, install the matching version of Indium alongside Sodium.
4. Temporarily remove Iris Shaders and test again if updating Sodium and downgrading Fabric API does not stop the crash.
